Question
Two billiard balls are initially traveling toward each otherat speeds of 1.10 m/s for ball 1 and3.70 m/s for ball 2. The balls undergo anelastic, head-on collision. Find their final velocities.ball 1 magnitude__________m/s ball 2 magnitude__________m/s Two billiard balls are initially traveling toward each otherat speeds of 1.10 m/s for ball 1 and3.70 m/s for ball 2. The balls undergo anelastic, head-on collision. Find their final velocities.
ball 1 magnitude__________m/s ball 2 magnitude__________m/s
Explanation / Answer
The velocity of the balls after the elastic collision isv1 = [u1(m1 - m2) +2m2u2/m1 + m2] and v2 = [u2(m2 -m1) + 2m1u1/m1 +m2] where m1 = m2,u1 = 1.10 m/sand u2 = -3.70 m/s
