You (A) are in a sledge sliding down an inclined plane. (Friction is neglected). An observer (B) at the foot of the plane looks at your initial position at the top of the slide and sees your energy as potential energy (mgh). You (A) slide down to the bottom of the plane and have a velocity of V0. So, the observer sees mgh = m
1) A boxer is struck by an opponent causing him to rotate about a vertical axis with an angular velocity of one revolution per second while his arms are extend horizontally with a 12-kg glove on each hand. He drops his hands to his sides hoping that the increase in angular velocity will cause the next blow to glance off him. If

There are two main types of collisions that you will study: elastic and perfectly inelastic. In an elastic collision, kinetic energy is conserved. In a perfectly inelastic collision, the particles stick together and thus have the same velocity after the collision. There is actually a range of collision types, with elastic and pe
