A 14.4-g wad of sticky clay is hurled horizontally at a 71-g wooden block initially at rest on a horizontal surface. The clay sticks to the block. After impact, the block slides d=11 m before coming to rest. The coefficient of friction between block and surface is µk=0.56. What was the speed of the block/blob just as it began to slide (use Conservation of Energy from the point at which the block/blob begins to move until it stops, recognizing that there was work done by a non-conservative force of friction as it slid to a stop)? 2. What was the speed of the blob just before the collision (use Conservation of Momentum from the point just before the clay collides with the wood to the point just after the collision, just as the block/blob begins to move as one unit)?

Definition Definition Force that opposes motion when the surface of one item rubs against the surface of another. The unit of force of friction is same as the unit of force.
