Problem: Use the figure below to answer the following question.  Assume that a cord is wrapped around the disk with a radius of 0.5 m.  The speed of the cord starts at 5 m/s and is accelerating at a rate defined by m/s2, where t is in seconds.  Neglect the mass and any friction of the disk.  LO 16a: What is the angular velocity of the disk at s?  Show your work.  Describe the direction beyond a simple +/-. Solution Units Direction

Problem: Use the figure below to answer the following questions.  Assume the block has a mass of 4 kg.  Initially, the block is at rest at a height of 0.7 m above Point B and the spring is at its free length. LO 14c: After the block falls onto the spring, how far is the spring compressed from its free length before the block comes to a rest? Show your work. Solution Units

Problem: Use the figure below to answer the following question.  Assume Ball A has a mass of 0.2 kg while Ball B has a mass of 0.5 kg.  Ball A is initially moving with a velocity of 5 m/s to the right while Ball B is initially moving to the right at 2 m/s.  The coefficient of restitution is . LO 15c: What are the velocities of Ball A and Ball B just after the impact?  Show your work.  Describe the direction beyond a simple +/-. Value Solution Units Direction
