A bullet of mass 4 g moving with an initialspeed 300 m/s is fired into and passes througha block of mass 7 kg. The block, initially at rest on a frictionless,horizontal surface, is connected to a spring offorce constant 440 N/m. If the block moves a distance 1.5 cm to theright after the bullet passed through it, findthe speed v at which the bullet emerges fromthe block. Answer in units of m/s. Additionally, find the magnitude of the energy lost in thecollision. Answer in units of J.
