An object of mass 25 kg is allowed to fall from a height of 15m. calculate its work done and potential energy.
Answers
Given:- m=25 kg, h= 15 m To find : W=?,P.E.=? Solution: P.E.=mgh P.E=25x9.8x15 P.E=3675 joule P.E.=W (Potential energy is the capacity to do work) W=3625 joule Therefore work done and potential energy of the object is 3625 joule
