which motion is this?

Deceleration

A car picks up speed at a constant acceleration from a standing start to a speed of 72 km/h in 5.0 s. The car has a mass of 1200 kg.

a Convert the speed into m/s.

b Calculate the acceleration of the car during picking up speed.

 At a certain time during acceleration, the resisting forces are 2000 N.

c Calculate the engine force at that time.
