Explanation:
Given
Object fall from a height of
Considering initial velocity to be zero i.e.
using
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
(b)Average acceleration
After falling 45 m, object strike the car and comes to rest after covering a distance of 0.5 m
again using
here final velocity will be zero i.e.
initial velocity
(c)time taken by it to stop
