A race car accelerates from 50 m/s to 75 m/s over a distance of 400 m. What is the race car's acceleration?
Answer:
[tex]a=3.90\ m/s^2[/tex]
Explanation:
Given that,
Initial velocity, u = 50 m/s
Final velocity, v = 75 m/s
DIstance, d = 400 m
We need to find the acceleration of the car. Let the acceleration of the car be a. We can use the third equation of motion to find it as follows :
[tex]v^2-u^2=2ad\\\\a=\dfrac{v^2-u^2}{2d}\\\\a=\dfrac{(75)^2-(50)^2}{2(400)}\\\\=\dfrac{3125}{2(400)}\\\\=3.90\ m/s^2[/tex]
So, the acceleration of the car is [tex]3.90\ m/s^2[/tex].

Two reindeer-in-training pull on a sleigh. Connie pulls with a force of 200 N at an angle of 20 degrees above the (positive) -axis, while Randolph pulls with a force of 800 N at an angle of 50 degrees ° below the positive) -axis. What is their resultant magnitude of the force on the sleigh?
Answer:
[tex]F_r \approx 978.3N[/tex]
[tex]\theta =44 \textdegree[/tex]
Explanation:
From the question we are told that
Connie pulls with a force of [tex]F_c=200 N[/tex]
At an angle [tex]\theta _c=20 \textdegree[/tex]
Randolph pulls with a force of [tex]F_R=800 N[/tex]
At an angle [tex]\theta _R=50 \textdegree[/tex]
Generally the horizontal axis can mathematically be represented as
[tex]f_x=f_ccos\theta _c+F_Rcos\theta _R[/tex]
[tex]f_x=200*cos20+800*cos50[/tex]
[tex]f_x=702.2N[/tex]
Generally the vertical axis can mathematically be represented as
[tex]f_y=f_csin\theta _c+F_Rsin\theta _R[/tex]
[tex]f_y=200*sin20+800*sin50[/tex]
[tex]f_y=681.24N[/tex]
Generally the resultant force [tex]F_r[/tex] is mathematically given by
[tex]F_r=\sqrt{f_x^2+f_y^2}[/tex]
[tex]F_r=\sqrt{702.1686119^2+681.2395832^2}[/tex]
[tex]F_r=978.3230731N[/tex]
[tex]F_r \approx 978.3N[/tex]
Generally the Direction [tex]\theta[/tex] of force is mathematically given by
[tex]\theta =tan^-^1(\frac{f_c}{f_y})[/tex]
[tex]\theta =tan^-^1(\frac{681.23}{702.16})[/tex]
[tex]\theta =44 \textdegree[/tex]

A boy is holding a ball 1 m from the ground with a force of 20 N. He holds it still for 60seconds. How much power in watts is being used in this situation?
Answer:
Power = 0.33 Watts
Explanation:
Given the following data;
Distance = 1m
Force = 20N
First of all, we would solve for the work done by the boy.
Workdone = force * distance
Substituting into the equation, we have;
Workdone = 20*1 = 20J
Now to find power;
Power = workdone/time
Power = 20/60
Power = 0.33 Watts.

A force is 10 and is used to move a box. It is moved a distance of 3 m. What is the work involved in moving the box?
Answer:
Workdone = 30Nm
Explanation:
Given the following data;
Force = 10N
Distance = 3m
To find the workdone;
Workdone = force * distance
Substituting into the equation, we have
Workdone = 10 * 3
Workdone = 30Nm.
Therefore, the work involved in moving the box is 30 Newton-meter.

What is the average velocity of someone who walks 3 km in a half hour, then 3 km in an hour, then 6 km in an hour and a half?
Answer:
The average velocity is 4 [tex]\frac{km}{hour}[/tex]
Explanation:
Velocity is the magnitude that relates the change in position with time. That is, the speed expresses the relationship between the space traveled by an object and the time used for it.
The average velocity relates the change in position with the time taken to effect said change through the expression:
[tex]velocity=\frac{distance}{time}[/tex]
In this case:
distance= 3 km + 3 km + 6 km= 12 kmtime= half hour + an hour + an hour and a half= 30 minutes + 1 hour + 1 hour 30 minutes= 0.5 hour + 1 hour + 1.5 hour= 3 hoursReplacing:
[tex]velocity=\frac{12 km}{3 hours}[/tex]
Solving:
velocity= 4 [tex]\frac{km}{hour}[/tex]
The average velocity is 4 [tex]\frac{km}{hour}[/tex]
Si se deja caer un carrito de una pista de coches sin friccion y su altura inicial es de 1.4 metros, cual es la velocidad maxima que puede alcanzar el carrito?
Answer:
[tex]5.241\ \text{m/s}[/tex]
Explanation:
m = Masa del coche
g = Aceleración debida a la gravedad = [tex]9.81\ \text{m/s}^2[/tex]
h = Altura = [tex]1.4\ \text{m}[/tex]
v = Velocidad del automóvil en la parte inferior de la pista
Aquí asumimos que el automóvil desciende verticalmente. La energía potencial del automóvil se completará convertida en energía cinética en la parte inferior de la pista ya que no hay pérdida de energía.
[tex]mgh=\dfrac{1}{2}mv^2\\\Rightarrow v=\sqrt{2gh}\\\Rightarrow v=\sqrt{2\times 9.81\times 1.4}\\\Rightarrow v=5.241\ \text{m/s}[/tex]
La velocidad máxima que puede alcanzar el coche es [tex]5.241\ \text{m/s}[/tex].

How much does the child weigh?
Answer:
W = 83 [N] (weight)
Explanation:
We must clarify that the system is in static equilibrium, in such a way that we must perform a sum of forces on the Y-axis equal to zero, in order to determine the downward force corresponding to the weight of the child.
∑Fy = 0
[tex]F_{1}+F_{2}-m*g=0\\18+65=m*g\\m*g = 83 [N][/tex]
And the mass can be determined as follows:
[tex]m*g=83\\m = 83/9.81\\m=8.46[kg][/tex]
The weight of the child is equal to 83 Newton.
Given the following data:
Upward force 1 = 18 NewtonUpward force 2 = 65 NewtonTo determine the weight of the child:
From the diagram, we can deduce that the system is in static equilibrium. Thus, we would resolve the horizontal component of the forces, in order to determine the downward force (weight of child).
Mathematically, the horizontal component of the forces is given by:
[tex]\sum F_y = 0\\\\F_1 +F_2 -mg=0[/tex]
Substituting the given parameters into the formula, we have;
[tex]18+65-mg=0\\\\83=mg[/tex]
Note: Weight = mg
Weight of child = 83 Newton.

Answer:
The frequency of a wave whose time period is 0.002 second is 500 Hz
Explanation:
Given,
Time period of wave = 0.002 seconds
We know,
Frequency = 1 / Time period
Substituting the values;
= 1 / 0.002sec
= 1000/2
Frequency = 500Hz
Hence,
The frequency of a wave whose time period is 0.002 second is 500 Hz

How do geologists construct the geologic column?
Answer:
They do this by joining pieces of different Rock sequences together from different places in the whole world.
Explanation:
Geologic columns are basically an arrangement of rock layers whereby the newest rocks are at the top while the oldest rocks will be at the bottom. Thus, it is like a timescale that's used to find the age of rock formation on the earth around the world.
it is easier to see clothes with pointed needle than a blunt one
Answer:
Explanation:
It is easier to see clothes with pointed needle than a blunt one because pressure exerted is more in a pointed needle as it occupies less space compared to blunt needle, A blunt has more surface area so the pressure exerted will less as compared to a pointed needle.
