A 5.00g bullet moving with an initial speed of 400m/s is fired into and passes through a 1.00 kg block. The block, initially at rest on a frictionless horizontal surface, is connected to a spring with a spring constant of 900N/m. If the block moves 5.00 cm to the right after impact, find the speed at which the bullet emerges from the block and the mechanical energy lost in the collision.
Imagine sitting on a steadily spinning merry-go-round, neither speeding up nor slowing down. Like all physics students, you have an identical twin, and your twin is sitting on the merry-go-round, but closer to the center than you. Which of you, if ei..
