What is the initial kinetic energy

Reference no: EM13314867

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. Stone 2 has a 0 m/s initial velocity. 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?
