A child's game consists of a block that attaches to a table with a suction cup, a spring connected to that block, a ball, and a launching ramp. The spring has a constant k. the ball has a mass m, and the ramp raises a height h. The spring is compressed a distance S in order to launch the ball. when the ball leaves the launching ramp its velocity makes and angle with respect to the horizontal.

1 Calculate the velocity of the ball when its leaves the launching ramp (both the magnitude and the direction. Be sure to specify your coordinate system)

2. The spring constant = 1000.0 N/m the spring compression is 4. cm the ball's mass is 55 g, the height of the ramp is 15 cm and the top of the table is 1.2 m above the floor. With what speed will the ball hit the floor?

2. Relevant equations

Delta y = V_{f}t+1/2gt^{2}

speed=distance/time

3. The attempt at a solution

I really do not have a clue where to start I have been thinking on how to solve it but all i have done is write down some equations that may be helpful but i really dont know if they are helpful in this problem. Can someone please help me? thanks
