#3 with complete solution
3. A stone is dropped from the roof of a building 100m high.
Find its final velocity when it reaches the ground and the
distance the stone falls in 3.5s?
4. With what velocity must a ball be thrown vertically upward in
to order to rise to a height of 50ft? How long will it be in
the air?
5. A batter hits a baseball with a velocity of 27.0m/s at an
angle of 30° above the horizontal. Find a) the time the ball is
in the air. b) the distance the ball travels before it hits the
ground. c) its maximum height?
