Projectiles assignment 1. A ball is thrown horizontally from the top of a building. It lands 2.3 s later, 35 m from the base of the building. How high is the building? 0 What was the ball's initial velocity? 0 What was its velocity as it hit the ground? (6 marks) 2. A golf ball is hit and leaves the tee with a velocity of 28.5 m/s, 32 above the horizontal, and lands on level ground (the landing is the same height as its origin) What is its total time in the air? What is its range? What is its maximum height? If there is a 5.5 m-high tree 60 m from the tee, does the ball go over it, or into it? Calculate by how much under or over the top of the tree. (8 marks)
