A car is moving down a street at 51 km/h. A child suddenly runs into the street. If it takes the driver 0.97 s to react and apply the brakes, how many meters will the car have moved before it begins to slow down?

Answer 1

51 km/h * 1000 m/km * 1/3600 h/s =
14.17 m/s.

d = v * t = 14.17 m/s * 0.97 s = 13.74 m.
