1. A 930-kg car traveling 56 km/h comes to a complete stop in 2.0 s. What is the

force exerted on the car during this stop?

The force exerted on the car during this stop is 6975N

Explanation:

Given-

Mass, m = 930kg

Speed, s = 56km/hr = 56 X 5/18 m/s = 15m/s

Time, t = 2s

Force, F = ?

F = m X a

F = m X s/t

F = 930 X 15/2

F = 6975N

Therefore, the force exerted on the car during this stop is 6975N
