During a pregame warmup period, two basketballs collide above the hoop when in the positions shown. Just before impact, ball 1 has a velocity v1 which makes a 35∘ angle with the horizontal. If the velocity v2 of ball 2 just before impact has the same magnitude as v1, determine the two possible values of the angle θ(θ1 < θ2) measured from the horizontal, which will cause ball 1 to go directly through the center of the basket. The coefficient of restitution is e = 0.65. Answers: θ1 = θ2 =

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.

The figure shows a 0.300 kg baseball just before and after it collides with a bat. Just before, the ball has a velocity v1 of magnitude 12.8 m/s and angle θ1 = 35°. Just after, it is travelling directly upward with velocity v2 of magnitude 10.0 m/s. The duration of the collision is 1.60 ms. (a) What is the magnitude of the impulse on the ball from the bat? kg⋅m/s (b) What is the direction (relative to the positive direction of the x axis) of the impulse on the ball from the bat? ° (counterclockwise from the +x axis) (c) What is the magnitude of the average force on the ball from the bat? N (d) What is the direction of this average force? ° (counterclockwise from the +x axis)

The cue gives the cue ball A a velocity parallel to the y axis. The cue ball hits the eight ball B and knocks it straight into the corner pocket. If the magnitude of the velocity of the cue ball just before the impact is 2 m/s and the coefficient of restitution is e = 1, what are the velocity vectors of the two balls just after the impact? (The balls are of equal mass.)
