| A body weighing 0.1 kg was thrown from a balcony vertically upwards at a speed of 3 m / s. The balcony is located at a height of 5 m from the surface of the Earth. What is equal at the moment of the throw: a) potential energy relative to the Earth’s surface; b) kinetic energy?
Ep = mgh = 0.1 * 5 * 10 = 5 J
Ek = mv ^ 2/2 = 0.1 * 9/2 = 0.45J
