Question

A body is moving with a speed of 5 m/s.In 5 sec the body comes to rest. Find acceleration and
distance covered by the body.​

Answer 1

v= 0

t= 5 sec

u=5m/s

v=u+at

=> 0 = 5+5×a

=>a=-1m/s^2

as retardation occurs so we will neglect negative sign.

we know S=D/T

S= 5 m/s

T= 5s

D=5×5=25m
