at a height of 5 m the total PE
= mgh
=2 x 10 x 5
=100 J
just before striking the ground the entire potential energy of the body changed into kinetic energy.
therefore
KE = PE = 100 J
= mgh
=2 x 10 x 5
=100 J
just before striking the ground the entire potential energy of the body changed into kinetic energy.
therefore
