Two carts of mass 50 kg have a collision. Before the collision, the first cart was travelling to the right at 4 m/s, and the 2nd cart was travelling to the left at 3 m/s. After the collision, the carts stick together. a) 10 pts What is the velocity of the carts immediately after the collision? b) 6 pts How much kinetic energy was lost in the collision? Where did this energy go? c) 10 pts After the carts have collided, they slide together across a rough patch of ground with which their coefficient of kinetic friction is 0.1. How far will they slide across this ground before they come to a stop? d) 4 pts Discuss whether your answer to part a passes the common sense test. Give specific reasons why or why not you think so.

Two carts are on an air-track where friction is negligible. The Incident Cart is moving at an initial velocity of 0.25080m/s, the target cart is at rest. The Incident cart has a mass of 995.8 g and the target cart has a mass of 490.3 g. The carts stick together, the final velocity after collision is 0.077302 m/s. The collision is considered inelastic. a) What is the Initial Momentum of the carts? b) What is the Final Momentum of the...

A 100kg cart moving at 25m/s rear-ends a 75kg cart moving at 10m/s. The two carts stick together, but during the collision a 10kg wheel on the 100kg cart breaks off and continues moving forward at 20m/s. Show work for all problems. 1) How fast are the carts going after the collision? (Be sure that your answer(s) clearly indicate direction as well as speed.) 2) Is this collision elastic? If yes, explain. If not, calculate the percentage of the initial...

Two low-friction physics demo carts collide on a horizontal track. The first cart, with a mass of 0.150 kg , is moving to the right with a speed of 0.800 m/s . The second cart, with a mass of 0.298 kg , is moving to the left with a speed of 2.27 m/s . The carts collide in an elastic collision, such that the total klinetic energy after the collsion is equal to the total kinetic energy before the collision....

A red cart with a mass of 250 g is initially moving east at 2.25 m/s. It collides with a blue cart with a mass of 350 g that is initially moving west at 0.750 m/s. After the collision the kinetic energy of the two carts together is 0.200 J more than before the collision, because the spring plunger of one of the carts pushes them apart during the collision. After the collision, the two carts are still moving along...

Two frictionless carts collide and stick together in a perfectly inelastic collision, due to a magnetic or mechanical coupling, on a one-dimensional track. Cart 1 has mass 200 grams and an initial velocity of 2 m/s. Cart 2 has mass 900 g, and is initially stationary. What is the velocity of the two carts together after the collision?

Two carts are rolling to the right along the same level track. Cart 1 (m1 = 3.81 kg) is in the rear, rolling at a speed of 6.25 m/s and catching up to cart 2, rolling at 3.07 m/s. Round final results to 3 digits. a) Cart 1 of course overtakes and collides with cart 2. Velcro pads on the carts make them stick together during the collision, after which they both continue rolling right, but at a speed of...
