Q1. An archer shoots an arrow with a velocity of 45.0m/s at an angel of 50.0 with the horizontal. An assistant standing on the level ground 150m downrange from the launch point throws an apple straight up with the minimum initial speed necessary to meet the path of the arrow. - What is the initial speed of the apple? b- At what time after the arrow launch should the apple be thrown so that the arrow hits the apple?

Q2. A jewel thief hides a diamond by placing it on the bottom of a public swimming pool. He places a circular raft on the surface of the water directly above and centered over the diamond.If the surface of the water is calm and the pool is h = 1.52 m deep, find out the minimum diameter of the raft that would prevent the diamond from being seen.
