Question

Two balls of equal mass (400g each) undergo a collision. One ball is initially stationary. After the collision, the velocities of the balls make angles of 22.5 degrees and 35.9 degrees relative to the original direction of the motion of the moving ball. If the initial velocity of the moving ball is 2.55 m/s [N45degreesE] what are the speeds of the balls after the collision?
for x-component:0.04*2.55sin45=0.04v1sin22.5+0.04v2sin35.9 for y-component:0.04*2.55cos45=0.04v1cos22.5+0.04v2cos35.9 1.803=0.38v1+0.59v2 1.803=0.92v1+0.81v2 solve for v1 and v2
