A 1kg ball is dropped of a 20m tall bridge onto tarmac. The ball experiences 2N of drag throughout its motion. The ground has a coefficient of restitution of 0.5. What is the maximum height the ball will reach after one bounce

Energy
GPE of the ball on the bridge: MGH = 1 * 9.81 * 20 =196 J
energy lost to drag = F * D = 2 * 20 = 40 J
Velocity of the ball just before impact =sqr(2*(196-40)/1) =17.66 m/s
