Practise identifying resistive forces, explaining why wet roads increase braking distance, and relating stopping distance to speed, deceleration and road conditions.
A car accelerates uniformly in a straight line from rest at time t=0. At t=3.2 s, the speed of the car is 13.0 m/s.
On another day, the car in (c) travels a longer distance while it decelerates from 13.0 m/s to 0 m/s. The deceleration is constant.
Suggest and explain what causes the stopping distance to increase. suggestion
