A 1200-kg car starts from rest and accelerates with constant acceleration, traveling 200 m in 9.00 s. what is the force of the road on the car during this acceleration?

First calculate the acceleration using the formula:

d = v0 t + 0.5 a t^2

where d is distance = 200 m, v0 = initial velocity = 0, t is time = 9s, a = acceleration (?)

200 = 0 + 0.5 * a * 9^2

a = 4.94 m/s^2

Force is mass times acceleration, therefore:

F = m a = 1200 kg * 4.94 m/s^2

F = 5,925.93 N
