The royal gorge bridge over the arkansas river is 310 m above the river. a 64-kg bungee jumper has an elastic cord with an unstressed length of 58 m attached to her feet. assume that, like an ideal spring, the cord is massless and provides a linear restoring force when stretched. the jumper leaps, and at at her lowest point she barely touches the water. after numerous ascents and descents, she comes to rest at a height h above the water. model the jumper as a point particle and assume that any effects of air resistance are negligible.

The ballistic pendulum was invented in 1742 by english mathematician benjamin robins. it consists of an initially stationary pendulum that moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. the known variables are the bullet's mass m, the pendulum's mass m, and the height to which the block and bullet swing, determined by the length of the pendulum l and final angle θ. two principles of physics are necessary to solve for the bullet's original velocity. what are these principles? conservation of momentum and newton's third law conservation of energy and conservation of angular momentum grade summary deductions 0% potential 100% conservation of momentum and newton's second law. newton's second law and conservation of angular momentum. conservation of energy and newton's third law conservation of momentum and conservation of angular momentum. conservation of momentum and conservation of energy conservation of energy and newton's second law.
