Two smooth billiard balls A and B each have a mass of 0.2 kg. Ball A strikes ball B with velocity (vA)1 = 1.5 m/s as shown, where ball B is originally at rest and the collision can be assumed to be perfectly elastic (that is, the coefficient of restitution e = 1). Do the following: (a) find the final velocity of each ball just after the collision, and (b) draw a diagram of the two balls just after the collision showing the approximate direction that each is travelling.

Two smooth billiard balls

A

and

B

each have a mass of

0.2 k g

. Ball

A

strikes ball

B

with velocity

{(v_{A})}_{1} = 1.5 m / s

as shown, where ball

B

is originally at rest and the collision can be assumed to be perfectly elastic (that is, the coefficient of restitution

e = 1

). Do the following: (a) find the final velocity of each ball just after the collision, and (b) draw a diagram of the two balls just after the collision showing the approximate direction that each is travelling.
