a stone with a mass of 0.100 kg rests on a frictionless, horizontal surface. a bullet of mass 2.40 g traveling horizontally at 525 m/s strikes the stone and rebounds horizontally at right angles to its original direction with a speed of 315 m/s .a stone with a mass of 0.100 kg rests on a frictionless, horizontal surface. a bullet of mass 2.40 g traveling horizontally at 525 m/s strikes the stone and rebounds horizontally at right angles to its original direction with a speed of 315 m/s . a) compute the magnitude of the velocity of the stone after it is struck.
b) compute the direction of the velocity of the stone after it is struck. (degrees from the initial direction of the bullet)

An artificial satellite circles the earth in a circular orbit at a location where the acceleration due to gravity is 6.03 m/s^2. determine the orbital period of the satellite.
