A crane is lifting a body to a height 'h' in time 't'. Find the relation between the power of crane to the speed at which it is lifting the object.



Power = work / time
           = force * displacement / time
           = mgh / t  = mas / t = force = speed

where m stands for the mass , g stands for acceleration due to gravity , h stands for height and t stands for time taken.
