A Red Rider bb gun uses the energy in a compressed spring to provide the kinetic energy for propelling a small pellet of mass 0.27 grams. By cocking the lever attached to the stock of the rifle, the spring (k = 1900 N/m) is compressed 9.5 cm from its equilibrium point. 1. What is the potential energy energy stored in the compressed spring?
2. What is the kinetic energy of the pellet when the spring is released?
3. What is the muzzle velocity of the bb?
4. If the rifle was modified so that the spring could be compressed twice as far, 19 cm, what would be the resultant muzzle velocity of the bb?

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
