A curling stone with a mass of 7.00 kg moves across the ice at a speed of 1.35 m/s in the positive x direction. It collides with another curling stone with the same mass (7.00 kg). After the collision stone 1 has a speed of 0.457 m/s at an angle of 54 degrees to the left of the x axis.
A) What is the initial kinetic energy?
B) What is the initial momentum (magnitude and direction)?
C) What is the speed and direction of stone 2 after the collision?
D) What is the total momentum perpendicular to the x axis after the collision?
