A marble is thrown vertically downward at an initial velocity 200cm/s hits the floor in 2.5 seconds ,At what height is the marble thrown?
1 answer
h = Vo*t + 0.5g*t^2.
h = 2*2.5 + 4.9*2.5^2 = 35.63 m.

A ball is thrown from a height of 10m with certain initial downward velocity. It hits the ground and loses 50% of its energy
Top answer:
initial energy = (1/2)m v^2 + m g (10) = m(.5 v^2+98.1) final energy = m(98.1) so 98.1 = .5(.5v^2
