A girl throws a ball vertically into the air with an initial velocity of 5.4m-s Assuming air resistance is negligible, what is the maximum height reached by the ball above the girl's hand? Take acceleration
due to gravity, g, to be 9.81 ms? Give your answer with an appropriate unit and to two significant
figures.

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.
