Conservation of Linear Momentum
... Study the finite time widths of the collision event. The carts slow, come almost to rest due to magnet repulsion, and then re-separate as the magnets continue to repel. The small bump in total momentum (brown curve) is presumably due to finite sampling time. Note that total kinetic energy (green cur ...

... A daredevil plans to bungee-jump from a balloon 65.0 m above a carnival midway. He will use a uniform elastic cord, tied to a harness around his body, to stop his fall at a point 10.0 m above the ground. Model his body as a particle, and the cord as having negligible mass and one that obeys Hooke’s ...
