What force is required to accelerate a 950 kilogram car 20 kilometers per hour to 45 kilometers per hour in 7 seconds? How far does the car travel during its acceleration?

change km/hr to m/s

acceleration= change in velocity/time

force= mass*a

distance=Vi^t+1/2 a t^2 or an easier way
distnace=avgvelocity*time where avg velocity =( intial+final)/2
