In a game of curling, a collision occurs between two stones of equal mass. The object stone is initially at rest. After the collision, the stone that is thrown hasa speed of 0.56m/s in some direction, represented by q. The object stone acquires a velocity vf2= 0.42m/s at an angle of f= 30.0o from the original direction of motion of the thrown stone. Determine the initial velocity of the thrown stone.
