A driver in a car traveling at a speed of
76 km/h sees a cat 109 m away on the road.
How long will it take for the car to acceler-
ate uniformly to a stop in exactly 106 m?

1. Scott

the average velocity during deceleration is __ (76 km/h + 0) / 2

the time is the distance divided by the average velocity

you will have to convert km/h to m/s to find the answer in s

17M/S2
