Q14 of 89 Page 51

A person travelling at 43.2 km/h applies the brake giving a deceleration of 6.0 m/s2 to his scooter. How far will it travel before stopping?


Initial velocity, u=43.2 km/h=12 m/s


Final velocity, v=0 km/h


a, acceleration=-6.0m/s2


We know


⇒


⇒


Hence it will travel 12 m before stopping
