Question

After a day of testing race cars, you decide to take your own 1502.5 kg car onto the test track. While moving down the track at 11.4 m/s, you suddenly accelerate to 30.2 m/s in 19.2 s.
What average net force have you applied to the car during that time?

Answer 1

force=mass*acceleration*mass(Vf-Vi)/time
