6.) A 'Newton's Cradle' consists of 7 identical metal balls which are free to swing back and forth. When two are pulled back and then released, they stop after colliding elastically with the other 5 balls. The two balls on the other end then swing upwards with the same speed as the first two balls. Using the conservation of momentum and mechanical energy, explain why only two balls move afterwards. Use words and/or equations to explain your answer.

A novelty collision device known as the executive toy consists of five identical metal balls. When one ball swings in, after multiple collisions, one ball swings out at the other end of the row of balls. When two balls swing in, two swing out; when three swing in, three swing out, and so on-always the same number out as in. Suppose that one ball, with mass m, swing in and collide with the next ball with a velocity v. Why...

There are 7 balls in a bag. They are identical except for color. 3 are red, 2 are white and 2 are blue. You are to draw 1 ball from the bag, note its color, and set it aside. Then you are to draw a second ball from the bag and note its color. a. Make a tree diagram to show all possible outcomes of the experiment. Label the probability associated with each stage of the experiment on the appropriate...

Consider an urn containing 3 red balls, 5 yellow balls, 7 blue balls, and 6 violet balls. If 4 balls are drawn at random, what is the probability of drawing one of each color? Suppose we draw 8 balls from the urn above. What is the conditional probability that 4 of them are blue with respect to the event that none of them are yellow?

An urn contains 4 white balls and 6 red balls. A second urn contains 7 white balls and 3 red balls. An urn is selected, and the probability of selecting the first urn is 0.1. A ball is drawn from the selected urn and replaced. Then another ball is drawn and replaced from the same urn. If both balls are white, what are the following probabilities? (Round your answers to three decimal places.) - (a) the probability that the urn...
