IP Assume that the brakes in your car create a constant deceleration of 4.7 m/s2 regardless of
how fast you are driving. If you double your diving speed from 17 m/s to 34 m/s , does the time required to come to a stop increase by a factor of two or a factor of four? Explain.

Part B: verify your answer by calculating the stopping times for initial speeds of 17 m/s. (Express answer using 2 sig figs)
