A) A solid disk rolls down an incline plane. The disk has a mass of 88 grams, a radius of 0.15 meters, and starts at a height of 4 meters above the bottom of the ramp. What is the magnitude of the velocity of the disk at the bottom of the ramp, in m/s?

B) A spring-loaded launcher has a spring constant of 230 N/m. The spring is compressed 4.5 cm. A 25 gram ball is launched exactly horizontally from the launcher. What is the speed of the ball immediately after launch?
