... 3. A person must move a large stone in her backyard. She gets a 20.0 kg plank that is 3.50 m long to use as a lever, and she wedges one end of the plank under the large stone. A smaller stone, 0.750 m from the large one, serves as a pivot. The plank makes an angle of 20.0° with the ground. When she ...

... be conserved. A misconception is that the collision will take less force to bounce off (elastic) than to stick together (inelastic). This isn’t true because bouncing involves a larger total force to both stop the current motion and reverse it. ● Looking at each ball’s momentum before and after the c ...
