At impact, most of the kinetic energy is transferred to elastic energy in the ball (by its deformation) and not to the floor. Some energy is also converted to other forms like heat and sound. These other forms of energy, are mostly losses and they are not recovered thus making the ball bounce back to a lower height.

WebAug 24, 2016 · I am not going to prove it mathematically, but it is not difficult to do from here. Now thinking about it the dropped ball starts at zero and ends up with some velocity... whereas the thrown ball ends up with zero velocity because the distance, time and acceleration are the same (except the acceleration is negative for the thrown ball). WebThe initial speed is zero because the balls are dropped and not thrown. Therefore, we can solve for time: time 2 = (2 × distance) / acceleration Substituting distance = 54 meters and acceleration = 9.8 meters/second 2, we get. time 2 = (2 × 54 meters) / (9.8 meters/second 2) = 11.0 seconds 2. The square root gives: time = 3.3 seconds WebApr 1, 2015 · The dropped third strike is a peculiar rule. 1 Three strikes and you are out seems a fundamental element of baseball, yet there is this odd exception.
