Time stone take to reach the ground when the bus is moving with constant acceleration of 2km/hr2 will be also 5 secs
Explanation:
Bus stationary does not have any vertical or horizontal velocity.
Moving Bus has horizontal velocity
but no vertical velocity.
hence in both cases vertical velocity is zero
and vertical acceleration is g
so in both cases time taken would be same.
Time stone take to reach the ground when the bus is moving with constant acceleration of 2km/hr2 will be also 5 secs
