A body is vertically upwards. If `t_(1)` and `t_(2)` are the times at which it is height h above the point of projection while ascending and descending, respectively, find (a) the velocity of projection and height h, (b) the maximum height reached by the body and (c ) the velocity of the body at height `h//2`.

A body is projected verticallt upwards. If t_(1) and t_(2) be the times at which it is at a height h above the point of projection while ascending and descending respectively, then:

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

A body is projected vertically upwards . The times corresponding to height h while ascending and while descending are t_(1)andt_(2) respectively . Then the velocity of projection is (g is acceleration due to gravity)

A particle is projected vertically upwards from a point O on the ground. It takes time t_(1) to reach a point A at a height h above the ground, it continues to move and takes a time t_(2) to reach the ground. Find (a) h, (b) the maximum height reached and (c ) the velocity of the partical at the half of maximum height.

A body is projected veritclaly upwards.The times corresponding to height h while ascending and while descending are t_(1) and t_(2) respectively. Then, the velocity of projection will be (take g as acceleration due to gravity)

A body is projected veritclaly upwards.The times corresponding to height h while ascending and while descending are t_(1) and t_(2) respectively. Then, the velocity of projection will be (take g as acceleration due to gravity)

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

A body is thrown vertically upward with velocity u . The ratio of times at which it is at particular height h is 1 : 2 . What is the maximum height reached by the body above point of projection ?

A body is projected vertically upwards and attains maximum height H. If the time to reach height 'h' and H are in the ratio of 1:3, then the ratio h/H is :
