1. The problem statement, all variables and given/known data After a day of testing race cars, you decide to take your own 1550 kg car onto the test track. While moving down the track at 10 m/s, you uniformly accelerate to 30 m/s in 10 s. What is the average net force that the track has applied to the car during the 10 s interval? 2. Relevant equations F=ma 3. The attempt at a solution Is it just (20/10)*1550? the only thing that confuses me is "the average net force that the track has applied to the car." The track applied to the car. Did the track apply the force?
