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?

An object is thrown vertically upwards with velocity of 20ms^(-1) . At what height will its kinetic energy and potential energy be equal? (g=10ms^(-2))
