Question

If you throw a 2.2 kg ball straight up by giving it 28 J of kinetic energy how much potential energy will it use at its highest point? Round your answer to the nearest whole number and include the appropriate unit.

Answer 1

Answer:

The potential energy possessed by the ball at the highest level is 28 J

Explanation:

The mass, m = 2.2 kg

The kinetic energy, KE = 28 J

KE = 0.5mv²

28 = 0.5(2.2)v²

28 = 1.1 v²

v² = 28/1.1

v² =

Note that, according to the law of conservation of energy, kinetic energy(KE) can be converted into potential energy (PE)

Therefore, KE = PE

PE = 28 J

The potential energy possessed by the ball at the highest level is 28 J
