Two identical billiard balls (mA = mB = 0.16 kg) can move freely on a horizontal table. Ball A has a velocity v→0 = 10 m/s→ and hits ball B, which is at rest, at a point C defined by θ = 30∘. The coefficient of restitution between the two balls is e = 0.9. Assume no friction. Determine: a. ) The velocity of each ball after impact (magnitude and angle with respect to horizontal of the page, don't forget to include the quadrant). b. ) The efficiency of the collision.

Two identical billiard balls (

m_{A} = m_{B} = 0.16 k g

) can move freely on a horizontal table. Ball

A

has a velocity

{\vec{v}}_{0} =

10 m / s \to

and hits ball

B

, which is at rest, at a point

C

defined by

θ = 30^{\circ}

. The coefficient of restitution between the two balls is

e = 0.9

. Assume no friction.

Determine: a.) The velocity of each ball after impact (magnitude and angle with respect to horizontal of the page, don't forget to include the quadrant). b.) The efficiency of the collision.
