An object of mass 40kg is raised to a height of 5 m above the ground. What is its potential energy? If the object is allowed to fall, find its kinetic energy when it is halfway down. (Take g=10ms^(-2) .)

An object of mass 8 kg is placed at a height of 5 m above the ground. What kind of energy does this object possess?

An object of mass 8 kg is placed at a height of 5 m above the ground. Find the amount of energy possessed by the object. (Take g=9.8 m/ s^2 )
