Answer to Question #317438 in Molecular Physics | Thermodynamics for Lamani

Question

A body of mass 0.6kg is thrown vertically upward from ground with a speed of 20ms-1. Calculate its potential energy at the maximum height

Answer 1

The potential energy at the maximum height is equal to the initial kinetic energy

$$E_p=\frac{mv_0^2}{2}=\frac{0.6*20^2}{2}\\ =120\:\rm J$$
