Solution Summary

The solution provides written explanation of the problem concerning the change in momentum of a billiard ball after hitting a rail in the answer space as well as an attachment featuring illustrative diagrams and further calculations.

A stationary billiardball, mass 0.17 kg, is struck by an identical ball moving at 4.1 m/s. After the collision, the second ball moves off at 60° to the left of its original direction. The stationary ball moves off at 30° to the right of the moving ball's original direction. What is the speed of each ball after the collision?

High speed stroboscopic photographs show that the head of a 184 g golf club is traveling at 52.9 m/s just before it strikes a 45.1 g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 42.2 m/s. Find the speed of the golf ball just after impact. Ignore the mass of the club handle.

In the figure (please see the attachment), a 0.420 kg ball is shot directly upward at initial speed 37.5 m/s. What is its angular momentum about P, 2.20 m horizontally from the launch point, when the ball is at the following heights?
i) at max height, ii) when it is halfway to the ground.
Also find the torque on the ball

Problem: Two billiardballs of equal mass move at right angles and meet at the origin of an xy coordinate system. One is moving upward along the y axis at 2.0 m/s, and the other is moving to the right along the x axis with speed 3.8 m/s. After the collision (assumed elastic), the second ball is moving along the positive y axis.

A white ball is moving and has a speed of 2 m/s and a yellow ball is at rest prior to an elastic glancing collision. After the collision the white ball has a speed of 1.23 m/s. To the nearest tenth of a degree, measured counterclockwise from east, what angle does it scatter at if the yellow ball is scattered at 280 degrees?

A 0.060 kg tennis ball, moving with a speed of 7.80 m/s has a head-on collision with a 0.086 kg ball initially moving away from it in the same direction at a speed of 3.10 m/s. Assume a perfectly elastic collision and take the initial direction of the balls as positive.
What is the velocity of the tennis ball after the collis
