A piece of cheese is sitting on a mousetrap which is set and ready to go. The spring in the mousetrap has a spring constant of 4 N/m, and is compressed by 0.08 m. The combined mass of the mousetrap bar and the cheese is 0.04 kg. If you drop something next to the mousetrap and it goes off, what is the velocity of the cheese at the instant it is released?
