Problem: A stone with mass 0.800 kg rests on a horizontal frictionless surface. A bullet with mass 0.0200 kg traveling horizontally at speed VAi strikes the stone and rebounds horizontally at a speed of VAf in an direction perpendicular to its original motion. After being hit by the bullet, the stone is moving at 6.00 m/s in a direction 30.0° from the original direction of motion of the bullet. What are the speeds VAi and VAf of the bullet before and after the collosion?Ans. VAi = VAf =
