Particle A and particle B are held together with a compressed spring between them.When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring.The mass of A is 2.00 times the mass of B, and the energy stored in the spring was 60 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of (a) particle A and (b) particle B?
In a ballistic pendulum demonstration gone bad, a 0.54 gg pellet, fired horizontally with kinetic energy 3.30 JJ , passes straight through the 400 gg Styrofoam pendulum block. If the pendulum rises a maximum height of 0.52 m , how much kinetic energy did the pellet have after emerging from the Styrofoam?

A Vulcan spaceship has a mass of 6.50 × 104 kg and a Romulan spaceship is twice as massive. Both have engines that generate the same total force of 9.50 × 106 N. If each spaceship fires its engine for the same amount of time, starting from rest and ignoring any change in mass due to whatever is expelled by the engines, calculate the energy of the Vulcan spaceship if the engines are fired for 102 s.
