1. A ball is thrown vertically upward from the top of a building that is 441 m high with an initial velocity of 44.1 m/s.
a) How high will it go from its release point?
b) What is the total time the ball is in air before it reaches the ground?
c) What is the velocity of the ball before it reaches the ground?
2. An arrow is shot into the air at an angle of 60 above the horizontal with speed of 30 m/s.
a) What are the x-components and y-componets of the velocity of the arrow 3.0 s after it leaves the bowstring?
b) What are the x-components and y-components of the displacement of the arrow during the 3.0 s interval?
