Unformatted text preview: spring. b) Calculate the maximum distance it moves up the incline plane. 3 3. A 20 kg block initially moving at 2.0 m/s collides with a 12 kg block initially at rest. After the collision the 20 kg block is moving at 1.0 m/s in a direction of 30 o with its initial direction. (Assume frictionless surface) (10 pts) a) Calculate the magnitude and direction of the velocity of the 12 kg block after the collision. b) Determine if the collision is elastic or inelastic. 4 4. In the figure below the 5.0 kg block is moving on a frictionless surface toward a 2.0 kg block initially at rest and connected to a spring. (15 pts) a) Calculate the maximum compression of spring after the collision. b) Calculate how much energy is lost during the collision . 2.0 kg 5.0 kg 5 m/s K=350 N/m...
