A body is in free fall vertically; find maximum height and time of flight.
A rock is thrown upward from ground level with initial upward velocity of 25 m/sec. The rock falls back down into a hole and strikes the bottom 35 meters below the ground surface.
Find the maximum height reached and the total flight time.
The general equation y(t) for a constant acceleration is:
(1) y = yo + vo t + .5 a t^2
In this example, acceleration a = ...
With a good explanation, the formulas and calculations are shown.
