Asked by dave
Ann is driving down a street at 58 km/h.
Suddenly a child runs into the street.
If it takes Ann 0.778 s to react and apply
the brakes, how far will she have moved before
she begins to slow down?

V = 58km/h = 58,000m/3600s = 16.1 m/s.
d = 16.1m/s * 0.778s = 12.53 m.
d = 16.1m/s * 0.778s = 12.53 m.
