Q1.An underwater diver sees the sun 50 degrees above horizontal. How high is the sun above the horizon to a fisherman in a boat directly above the diver?

Q2. A wrecking ball is suspended from a 2.5-m-long cable that makes a 25 angle with the vertical. The ball is released and swings down. What is the ball's speed at the lowest point?

Q3. A vertical spring with a constant of 450 N/m is mounted on the floor. From straight above, a .30 kg block is dropped from rest. It collides with and sticks to the spring that is compressed by 2.5 cm in bringing the block to a momentary halt. Assume air resistance is negligible; from what height (in cm) above the compressed spring was the block dropped?
