A 6.0-kg block situated on a frictionless incline is connected to a light spring (k = 200 N/m), as shown. The block is released from rest when the spring is unstretched and slides down 0.3 m. The pulley is frictionless and has negligible mass. (15 points) i. ii. iii. What is the initial energy of the system. What is the final energy of the system. Determine the speed of the block when it has moved 0.30 m down the plane? k
