A 1100kg car starts from rest, accelerates for 5 seconds. The magnitude of acceleration is (a)= 4.6m/s2. find the average power generated by the net force that accelerates the vehicle? what do i do here
i know that F=ma= 1100x4.6=5060=F and
Wnet = 1/2mvf2-1/2mvi2 since it starts from rest Vi= 0
so 1/2mvf2 =(1/2)(1100)(4.6?)=11638 im a doing this right if not can someone tell me what to do?
