Ann is driving down a street at 58 km/h. Suddenly a child runs into the street. If it takes Ann 0.742 s to react and apply the brakes, how far will she have moved before she begins to slow down? Answer in units of m.

Answer 1

sorry - I misread your other post. The answer here is much simpler.

58 km/hr = 16.11 m/s

distance = speed * time = 16.11 m/s * 0.742s = 11.95m
