A ball is thrown horizontally from the top of a building 17.6 m high. The ball strikes the ground at a point 67.7 m from the base of the building. The acceleration of gravity is 9.8 m/s^2

1. Find the time the ball is in motion.

Answer in units of s.

2. Find the initial velocity of the ball. Answer in units of m/s.

3. Find the x component of it's velocity just before it strikes the ground. Answer in units of m/s.

4. Find the y component of it's velocity just before it strikes the ground. Answer in units of m/s.
