Consider the collision between two hockey pucks in the figure below. They do not stick together. Their speeds before the collision are v1i = 30 m/s and v2i = 14 m/s. It is found that after the collision one of the pucks is moving along x with a speed of 5 m/s. What is the final velocity of the other puck? magnitude m/s direction ° counterclockwise from the +x-axis.
