I shoot a basketball that has a mass of 0.5 kg, off a table using the spring. The spring constant is 10,000 N/m and the spring is compressed a distance 5 cm before the ball is released.

a) How fast is the ball moving after it leaves the spring?

b) How fast is the ball moving before it hits the ground, which is 1 m below the top of the table?

c)The ball bounces and looses 30% of it’s total energy. What is the max height of the ball after the bounce?

Ball A (m 0.5 kg, I 0.7 MR2) is held at rest against a spring, compressed by a distance x-40 cm. The ball is released and move along a frictionless surface (Ho 4 m) until it collides with ball B (m- 0.25 kg, I- 0.5 MR2) which is at rest. After the collision, the two balls roll down a track (which has friction!) and leaves the track at a height, H,- 1m. Ball B goes to a height of HB-5m...
