Quiz (10 minutes) 1. A lump of clay of mass m is traveling with speed v when it hits another lump of clay that is initially at rest. The lumps of clay stick together after the collision. How much of the initial kinetic energy is “lost” into heat and other forms of internal energy? 2. A hoop of mass M and radius R is rolling along the ground (in the +x direction) with speed v. What is its total energy? What is its total
