A body of `200 g` begins to fall from a height where its potential energy is `80 J`. Its velocity at a point where its kinetic and potential energies are equal `(in m//s)`.

A body of 200g begines to fall from a height where is potential energy is 80 j. Its velocity at a point where kinetic and potential energies are equal is

For a body its elastic potential energy is equal to

" A body is dropped form a height h.When loss in its potential energy is "'U'," its velocity is "V" .The mass of the body is "

A spring when stretched by 2 mm its potential energy becomes 4 J. If it is stretched by 10 mm, its potential energy is equal to

a long spring is stretched by 4 cm, and its potential energy is 80 J. If the spring is compressed by 2 cm, its potential energy will be

When a body is projected vertically up. At some point P at height h its kinetic energy is twice of potential energy at that point. At what height its potential energy is twice that of kinetic energy?
