A 1200 kg car on a horizontal surface starts from rest and accelerates uniformly to 72 km/h in 20.0 s. Friction exets an average force of 450 N on the car during this time.

a) what is the net work done on the car

b) how far does the car move during this acceleration

c) what is the net force exerted on the car during this time

d) what is the forward force exerted on the car as an engine, power train, and wheels pushing back on the road

help! i tried figuring it out and i get so stuck
