When you play billiards, can you predict the velocities of the billiard balls after a collision if you know the velocity of a moving ball before the collision? assume the velocity of the first ball before the collision is v1i. the velocity of the second ball before the collision is zero. the balls have the same mass. a. find the velocity of the first ball after the collision. assume that the collision is head-on and elastic and that rotational motion can be ignored. express your answer in terms of v1i. b. find the velocity of the second ball after collision in terms of other velocities. express your answer in terms of v1i.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
