Question

A car of mass 1200kg accelerates from rest to a speed of 8m/s in a time of 2sec calculate the forward force acting on the car while is accelerating

Answer 1

Answer:

Explanation:

acceleration=v/t=8/2=4 m/s^2

force = ma = 1200* 4=4800 N

please mark as brainliest.

Answer 2

Answer:

Explanation:

Force =mass×change in velocity/t

Ma= mv/t. (a=v/t)

F= 1200×8/2=4800N
