A particle is falling freely from a height. When it reaches 10m height from the ground its velocity is `v_(0)`.It colloids with the ground and loses 50% of its energy and rises back to height of 10 m. The velocity `v_(0)` is

A ball is falling freely from a certain height. When it reached 10 m height from the ground its velocity is v_(0) . It collides with the horizontal ground and loses 50 % of its energy and rises back to height of 10 m . The value of velocity v_(0) is

A ball falls under gravity from a height of 10 m with an initial downward velocity u. It collides with the ground, losses 50% of its energy in collision and then rises back to the same height. The initial velocity u is

A ball falls under gravity from a height of 10 m with an initial downward velocity u. It collides with the ground, losses 50% of its energy in collision and then rises back to the same height. The initial velocity u is

A ball is thrown vertically downwards from a height of 20m with an intial velocity v_(0) . It collides with the ground, loses 50% of its energy in collision and rebounds to the same height. The intial velocity v_(0) is (Take, g =10 ms^(-2) )

A ball falls under gravity from a height of 10m with an initial velocity. It collides with the ground,loses 50% of its engery and then rises to the same height.Find the initial velocity.

A ball falls under gravity from a height of 10m with an initial downward velocity u. It collides with the ground, loses 50% of its energy in collision and then rises back to the same height. Find the initial velocity ''u''.

A ball falls under gravity from a hight of 10 m height of 10 m wioth an initial downward velocity u .If collides with the gound , loses 50% of its energy in collision and then rises back back to the same heighrt .Find the initial velocity u.
