Answer:
Acceleration.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
The S.I unit for measuring acceleration is meters per seconds square (m/s²).
Hence, 10 m/s^2 is an example of acceleration.
Mr. Rudman drives his race car for 4 hrs at 150
miles/hr. How far will he travel?
PLZ Help!! Answer the Question Below:
Answer:
18.78 m/s.
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 50 kg
Initial velocity (u) = 0 m/s
Height (h) of cliff = 18 m
Acceleration due to gravity (g) = 9.8 m/s²
Final velocity (v) =?
The velocity with which the diver reach the water can be obtained as follow:
v² = u² + 2gh
v² = 0² + (2 × 9.8 × 18
v² = 0 + 352.8
v² = 352.8
Take the square root of both side
v = √352.8
v = 18.78 m/s
Thus, the diver will reach the water with a velocity of 18.78 m/s.
How much pressure is being exerted by blood cells that are applying 375N of force over 25.5m2 of your body’s blood vessels?
PLS HELP MEEE
Answer:
Pressure = 14.71N/m²
Explanation:
Given the following data;
Force = 375N
Area = 25.5m²
To find the pressure;
Pressure = force/area
Pressure = 375/25.5
Pressure = 14.71N/m²
Therefore, the amount of pressure that is being exerted by blood cells is 14.71 Newton per meter square.
