3. A ball thrown horizontally from the edge of the top of a building 49.0 m high strikes the ground 24.5 m from the foot of the building. Find the (a) time it takes the ball to reach the ground (b) initial velocity of the ball (c) velocity just before the ball strikes the ground. Clue: a. Use y = Vot + 1/2 gt2 b. Use the formula for intital velocity. c. Use answer in b for Vx. For Vy use equation Vy = Voy + gt Get the pythagorean relation and angle. Write also the components of the velocity.
