A ball is released from height `80 m`. When the ball is at height `60 m`, it explodes in two parts of mass ratio `1 : 2`. One of them moves horizontally with speed `20 m//s`. The distance between the two pecies on the ground is

A ball falls freely from a height of 45m. When the ball is at a height of 25m, it explodes into two equal piece. One of them moves horizontally with a speed of 10ms^(-1) . The distance between the two pieces on the ground is

A ball starts falling under the effect of gravitational force from a height of 45m. When it reaches a height of 25 m. When it reaches a height of 25 m it explodes into two pieces of mass ratio 1:2 . There is no change in the vertical motion of the piece after the explosion but they acquire horizontal velocity. If the heavier piece gains a horizontal velocity of 10ms^(-1) , then the distance between the two pieces when both of them strike the ground is

A ball is thrown horizontally with a speed of 20 m//s from the top of a tower of height 100m Time taken by the ball to strike the ground is

A ball released from rest from the roof of a building of height 45 m at t = 0. Find the height of ball from ground at t = 2s.

A ball is released from a height of 10 m. If it loses 20% of its energy on hitting the ground, the height to which it bounces is

A ball of mass 2 kg is projected horizontally with a velocity 20m/s from a building of height 15m. The speed with which body hits the ground is :
