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 don’t two ball swing out at the other end with a velocity of v/2? Clearly establish the reasoning and physical principles to receive full credit.

Can someone explain to me what laws are being used here and how it relates to the question? Thank you.

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.

In an momentum experiment involving the collision of two metal balls.... one at rest and the other that has an initial velocity moving in a projectile path, how would you determine the maximum height of the ball that is hit? Also, how do you find the velocity of the projectile (initially moving) ball just after the collision? Thanks!

A device consists of 8 balls with mass .6kg attached to the ends of low mass spokes of length 1.8m, so that radius of rotation is .9m. it's held in a verticasl plane,frictionles axle. A lump of clay falls and sticks to one of the balls when the spoke attatched to the ball is at 45 degrees to the horizonal. Just before im pact the clay mass has speed of 5m/s, and the wheel is rotating counter clockwise with an...

Two identical metal spheres attract each other with a force of 7.00 × 10−6 N when they are 3.00 cm apart. The spheres are then touched together and then removed to the original separation where now a force of repulsion of 2.00 × 10−6 N is observed. What is the charge on each sphere after touching and before touching?
