I drop a 55-g golf ball from 2.50 m high.It rebounds to 1.65 m.How much energy is lost?

Question

Quizplus · Accepted Answer

The energy lost during the bounce can be calculated by finding the difference in potential energy before and after the bounce. The potential energy (PE) is given by PE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s^2), and h is the height in meters.Initial potential energy = mgh (before the bounce) = 0.055 kg * 9.8 m/s^2 * 2.50 m = 1.3475 JFinal potential energy = mgh (after the bounce) = 0.055 kg * 9.8 m/s^2 * 1.65 m = 0.89145 JEnergy lost = Initial potential energy - Final potential energy = 1.3475 J - 0.89145 J = 0.45605 JRounded to two decimal places, the energy lost is approximately 0.46 J.
