The tendency of a body to oppose any change in its state of rest is known as inertia of rest.
Example :
1 ) A person standing in a bus Falls backward when the bus suddenly starts moving forward.
Reason》When the bus Moves, the lower part of his party begins to move along with the bus by the upper part of his body continues to remain at rest due to inertia of rest.
That is why, a person Falls backward when the bus suddenly starts.

Inertia
A bowling ball has a higher inertia than bowling pins, as it weighs significantly more than the pins.
if you convert these into miles per hour 50 m/s would be higher, since
50 m/s = 111.85 mph and
140 km/h = 86.99 mph
I have the same thing for homework
Answer:
the impulse experienced by the passenger is 630.47 kg
Explanation:
Given;
initial velocity of the car, u = 0
final velocity of the car, v = 9.41 m/s
time of motion of the car, t = 4.24 s
mass of the passenger in the car, m = 67 kg
The impulse experienced by the passenger is calculated as;
J = ΔP = mv - mu = m(v - u)
= 67(9.41 - 0)
= 67 x 9.41
= 630.47 kg
Therefore, the impulse experienced by the passenger is 630.47 kg
