Find the energy possessed by a bird of 5 kg moving at a constant height of 10 m from the ground with a speed of 2 m `s^(-1)`. (Take `g = 10 m s^(-2)`)

Find the energy possessed by an object of mass 10 kg when it is at a height of 6 m above the ground.Given, g = 9.8 m//s ^2

A platform is moving upwards with a constant acceleration of 2 m s^-2 . At time t = 0 , a boy standing on the platform throws a ball upwards with a relative speed of 8 m s^-1 . At this instant, platform was at the height of 4 m from the ground and was moving with a speed of 2 m s^-1 . Take g = 0 m s^-2 . Find (a) when and where the ball strikes the platform. (b) the maximum height attained by the ball from the ground. ( c) the maximum distance of the ball from the platform.

The work done to move an object of mass 2 kg to a height of 50 m from the ground is ______ J. (g = 10 m s^(-2))

Find the energy possessed by a stationary object at a height of 6 m and with a mass of 50 kg. (g = 10m//s^2)
