0.110kg stone rests on a frictionless, horizontal surface. A bullet of mass 8.00g , traveling horizontally at 340m/s , strikes the stone and rebounds horizontally at right angles to its original direction with a speed of 190m/s.
Part A Compute the magnitude of the velocity of the stone after it is struck.
Part B Compute the direction of the velocity of the stone after it is struck Part C Is the collision perfectly elastic?
