When a body is projected vertically up from ground, its velocity is reduced to 1/3 rd of initial velocity at height 'y' above the ground. Then maximum height reached by the body is

When a body is projected vertically up from the ground, its velocity is reduced to (1/3)^rd of its initial value at height y above the ground. The maximum height reached by the body is

When a body is projected vertically up from the ground, its velocity is reduced to (frac(1)(3))^(rd) of its initial value at height y above the ground . The maximum height reached by the body is

A body projected vertically with a velocity 'u' from ground. Its velocity

A body is projected vertically from the surface of the earth of radius R with velocity equal to half of the escape velocity. The maximum height reached by the body is

A body is projected vertically up from ground with a velocity u so as to reach maximum height 'h'. At half of the maximum height its velocity will be

A body is projected vertically upwards from the ground. On reaching the greatest height
