Answer:
A.Running 50 m along a straight track
Explanation: Running 50 m along a straight track is a real-world example of linear motion.Linear motion means moving along a (straight) line, a direct and straight line from point A to point B.All the other proposed answers (A,B,C) involve a curve. The two rock examples will curve due to gravity and running around a curve on a track isn't a straight line.I hope that helps you understanding the principle of linear motion.
Answer:
A. Running 50m along a straight trackExplanation:
Linear motion is the motion that is natural to an object: moving in a straight line. An object not affected by any force will continue indefinitely in a straight line.Joey is riding in an elevator which is accelerating upwards at 2.0 m/s2. The elevator weighs 300.0 kg, and Joey weighs 60.0 kg. What is the tension in the cable that pulls the elevator upwards?
A) 4200 N
B) 9800 N
C) 3700 N
D) 5200 N
4200 N is the tension in the cable that pulls the elevator upwards.
The correct option is A.
What does tension ?Tension is the force that is sent through a rope, thread, or wire whenever two opposing forces pull on it. Along the whole length of the wire, the tensile stress pulls equally on all objects at the ends. Every physical object that comes into contact with that other one exerts force on it.
Briefing:We employ the following formula to determine the cable's tension.
Formula:
T = mg+ma............ Equation 1
Where:
T is the cable's tension.
M = Mass of the elevator and the Joey
Accelerating with a
g = Gravitational acceleration
Considering the query,
Given:
m = (300+60) = 360 kg
a = 2 m/s²
g = 9.8 m/s²
Substitute these values into equation 2
T = (360×9.8)+(360×2)
T = 3528+720
T = 4248 N
T ≈ 4200 to the nearest hundred.

You see a flash of lightning, and then 15 seconds later you hear thunder. How far away is the lightning?.
The lightning is 3miles far away.
The distance between the lightning strike and the thunderclouds is roughly 10 miles. The presence of thunder is a sign that a storm is approaching you if you can hear it. The air temperature in the path of a lightning strike can climb to 50,000 degrees Fahrenheit.You can figure out how far away the lightning is from you since lightning strikes instantly and thunder takes around 5 seconds to travel a mile.By calculating the seconds between the lightning flash and the sound of thunder and multiplying that number by 5, it is possible to determine the distance in miles to the lightning. 0 seconds is very close, 5 seconds is one mile, and 15 seconds is 3 miles.

The temperature of waste heat exhausted is 483.83 °C.
A Carnot heat engine is a heat engine that operates at the Carnot cycle. The simple version of this engine turned into evolved by Nicolas Léonard Sadi Carnot in 1824.
The Carnot engine is a theoretical thermodynamic cycle proposed by means of Leonard Carnot. It estimates the maximum possible efficiency that a heat engine all through the conversion manner of heat into work and, conversely, operating between reservoirs can possess.
calculation:-
1 kcal = 4.186 k J.
So the engine efficiency eta = 510/930 × 4.186 = 0.13305
T hot = 600 + 273.15 = 873.15 K
From the Carnot equation = (T hot-T cold) /T Hot,
so
T cold = T hot(1-eta)

The final speed when the mass is 40,000kg height is 2.5km and 500,000N of force is 176.8 m / s
According to Newton's second law of motion,
F = m a
F = Force
m = Mass
a = Acceleration
m = 40000 kg

The height to which the toy gun can shoot a 0.0125 Kg toy bullet is 1.29 m
How to determin the heightWe'll begin by determine the energy of the spring. This can be obtained as follow:
Spring constant (K) = 350 N/mCompression (e) = 0.0300 mEnergy (E) =?E = ½Ke²
E = ½ × 350 × 0.03²

A compressive force of F-5000 N is applied to the right end of the brass cylinder. Find the amount by which the length of the stack decreases.
Let xc for the copper cylinder, xb for the brass cylinder.
The total compression will be xc + xb
Young modulus Y of a material is given Y = FL/ADL
A = area
DL = change of length
L = original length
F = force
so here we apply the same Force for both copper and brass
so F/A = 9200/(3.14 * 0.0022* 0.0022)
F/A = 695.35 MN/m^2
For the copper cylinder:
strain = 695.35e6/(1.1e11 ) = 6.32 *10^-3
xc = strain*length = 3*6.32 e -3 = 18.96
For the brass cylinder

xb = 31.8
Total change in length = xb + xc = 50.76 *10^-3 cm.

A race car entering the curved part at the Daytona 500 drops its speed from 85m/s to 80m/s in 2s. If the radius of the curved part of the track is 316m, the total acceleration of the race car at the beginning is 22.86m/s² and at the ending of reduction of speed is 20.25m/s².
The car is moving in the curved part and hence possesses centripetal acceleration. It is given by the formula, a=v²/r
where, a is centripetal acceleration in m/s²
v is velocity in m/s
r is radius in metres
It is given that the velocity of the car in the beginning is 85m/s (v₁) and the velocity of the car in the ending is 80m/s (v₂).
Now, let us find out the acceleration of the car in the beginning (a₁) and in the ending (a₂).
a₁=(v₁)²/r = (85)²/316 = 22.86m/s²
a₂=(v₂)²/r = (80)²/316 = 20.25m/s²

A rightward force of 12.0 N is applied to a 2.0-kg object to accelerate it across a horizontal

Answer:
below
Explanation:
Net accelerating force becomes 12-8 = 4 N
F = ma
4 = 2 * a
a = 2 m/s^2
The object encounters 8.0 N of friction. The object's acceleration is 2 m/s².
What is acceleration?Acceleration is the rate at which the speed and direction of a moving object change over time. A point or object moving straight ahead is accelerated when it accelerates or decelerates.
Even if the speed is constant, the motion on a circle accelerates because the direction is constantly shifting.
The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains."
Net accelerating force becomes 12 - 8 = 4 N
The formula for force is

F = ma
4 = 2 x a
a = 2 m/s²

Answer:
Impulse is the amount of force put on an object in a certain amount of time. Therefore when kicking a ball and "kicking through it" it extends the period of time this force is applied in turn increasing its impulse. Impulse is equal to change in momentum. momentum is equal to mass times velocity and since mass of the ball doesn't change therefore the velocity is increased and performance increased.
