Use the worked example above to help you solve this problem. A ball is thrown upward from the top of a building at an angle of 30.0° to the horizontal and with an initial speed of 24.0 m/s. The point of release is h = 46.0 m above the ground.
(a) How long does it take for the ball to hit the ground?
s
(b) Find the ball's speed at impact.
m/s
(c) Find the horizontal range of the ball.
m
