Aball with a mass of 0.5 kilograms is lifted to a height of 2.0 meters and dropped. it bounces back to a height of 1.8 meters.
the energy of the ball has been reduced by (0.98, 8.82, 9.8) joules after bouncing back. this reduction happens because potential energy transforms to (kinetic, light, thermal energy).
hint: use pe = m × g × h where g = 9.8 m/s2.
