Question

2) An object of mass 5 kg is dropped from a height of 10 m, find its kinetic energy. g = 10 m/s²

Solution

Dear Student ,
When an object is dropped from a certain height then at the time it touches the ground the object's potential energy is totally converted in to kinetic energy .
$H e n c e t h e k i n e t i c e n e r g y i s, E = m g h = 5 \times 10 \times 10 = 500 J$
