1. The problem statement, all variables and given/known data .100-kg stone rets on a frictionless, horizontal surface. A bullet of mass 6.00g, traveling horizontally at 350 m/s, strikes the stone and rebounds horizontally at right angles to its original direction with a speed of 250 m/s. (a) Compute the magnitude and direction of the velocity of the stone after it is struck. 2. Relevant equations Kfinal=Kinitial Pfinal=Pinitial 3. The attempt at a solution My problem with this question is that I cannot visualize it so I do not know how to try and solve it. I am confused because the bullet is initially traveling horizontally, but then is rebounding horizontally but at a right angle to the horizontal...? I thought it was just giving me the x-component of velocity for the bullet, but wouldn't the situation described be vertical?
