Question

Consider a rubber ball freely falling from a height $h equals 4.9 blank m$ onto a horizontal elastic plate. Assume that the duration of collision is negligible and the collision with the plate is totally elastic. Then the velocity as a function of time will be

The correct answer is:

$h equals fraction numerator 1 over denominator 2 end fraction g t to the power of 2 end exponent comma blank$ (paraboli(c)
$v equals negative g t$ and after the collision, $v equals g t$ (straight line)
Collision is perfectly elastic then ball reaches to same height again and again with same velocity
