A 3 kg stone is dropped from a height of 100 m . Find its kinetic and potential energies when it is 50 m from the ground.
| Certified Educator
The stone is initially at a height of 100 m from where it is dropped. The gravitational potential energy of an object with mass m at a height h from the ground is PE = m*g*h where g is the acceleration...
