Question

a bus is moving at a speed of 5m/s is stopped In 2seconds by applying break calculate the retardation produced in bus

Answer 1

initial velocity=5ms-¹

final velocity =0ms-¹

time 2sec

a=0-5/2
a=(-2.5)ms-²

- shows retardation means negative acceleration

Answer 2

initial velocity=5ms-¹

final velocity =0ms-¹

time 2sec

a=0-5/2

a=(-2.5)ms-²

- shows retardation means negative acceleration
