Question

A scooter moving at a speed of 10m/s is stopped by applying brake which produce a unform acceleration of -0.5m/s square. How much distance will be covered by the scooter before it stops

Answer 1

Here speed = 10m/s
acceleration = 0.5m/s square
a= v-u/t
t=10/0.5
t=20s
S=d/t
10=d/20
d=200m
