Work is required to lift a body through a height from the ground, Calculate the work done in lifting a body of mass 10 kg to a height of 10m above the ground.

Calculate the potential enrgy of a body of mass 50 kg raised to a height of 4 m above the ground. If the body falls down under gravity freely, then what will be its velocity when it just touches the ground ? (Given g=9.8 m//s^(2))
