A billiard ball moving horizontally, labeled 1, strikes another billiard ball at rest, labeled 2. Before impact, ball 1 was moving at a speed of 2.70 m/s, and after impact it is moving at 0.40 m/s at 45 counterclockwise from the direction of the initial velocity. If the two balls have equal masses of 160 9, what is the velocity of ball 2 after the impact? (Assume ball 1 initially moves along the +Xaxis. Enter the magnitude in m/s and the direction in degrees counterclockwise from the +x axis.) magnitude m/s direction [: counterclockwise from the +Xaxis
