A body of mass 2 kg is dropped from a height of 5 m. Calculate the potential energy lost (take g = 9.8 m/s²).
Explanation
The potential energy lost is equal to the initial potential energy, which is given by mgh. Here, m = 2 kg, g = 9.8 m/s², and h = 5 m. So, the potential energy lost is 2 * 9.8 * 5 = 98 J.
