A truck accelerates uniformly from rest to 21.5m/s in 5.7sec along a level stretch of road. Determine the average power required to accelerate the truck for the following values of the weight (ignore friction)

Question

a) 1.00x10^4 N
b) 1.45x10^4 N

I used constant acceleration equation to find the displacement and used P=Fx(d/t) equation and got
a) 107543.85W
b)155938.59W
Can someone tell me if I did this question right? Thanks!
