Solution: Deceleration:Suppose a pumpkin is pushed along the icy surface and its velocity decreases at a constant rate. In this situation, the rate of change of velocity is called its deceleration. The direction of the deceleration will be opposite to the motion of the pumpkin. Given values: Initial speed of the car, Final speed speed of the car, Reaction time
