Question

A book mass 3 kg is dropped from a height of 16 m. What is the potential energy of the book just before falling?also calculate kinetic energy of the book just before hitting the ground​

Answer 1

mass= 3 kg

h=16m

g=10m/s^2

potential energy=mgh

=3×16×10

=480J

Also potential energy = kinetic energy therefore kinetic energy=480 J
