You are playing with two stones that slide across a smooth sheet of ice. One stone has a mass of 19.19 kg, and is traveling with a velocity 1.2x̂ + 1.2ŷ m/s. The other has a mass of 17.78 kg and is initially at rest. After the collision, the 19.19 kg stone has a velocity -1.2x̂ + 2.0ŷ m/s. What is the x component of velocity of the 17.78 kg stone after the collision? Report your result in meters per second, rounded to one decimal place

Two carts roll smoothly on a track. One cart has a mass m and is moving at a velocity v. The other cart has a mass 2m and is moving in the same direction at a velocity 0.53*v. The cart that is moving faster rear-ends the slower cart, and the two stick together. What is their velocity after the collision? Answer in terms of v, entering the coefficient rounded to two decimal places

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 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 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 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...

Consider a collision between two carts, one of mass mA= 5 kg and the otherof mass mB= 7 kg, on a frictionless track. (A). Find the final velocity of Cart A, if both objects are initially moving in opposite directions toward each other at 12 m/s, and Cart B completely stops due to the collision. (B). Is this an elastic or inelastic collision? Why?

1. Assume the cart has a mass of m, and that the carts are oriented so that their velcro bumpers face each other. one of the carts is placed on middle of the track and the other on the far left of the track. suppose you push the cart gently on the left side toward the cart at rest so that the carts collide. mass of cart is .05123 kg a) if the velocity of the moving cart is v...

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....

Two carts are on a flat surface of negligible friction. Cart A has a mass of 328 [grams] and cart B has a mass of 315 [grams]. Then an object of unknown mass is placed in one cart A and the two carts experience a completely inelastic collision. At the instant before collision Cart B moves .3m in .3 seconds and Cart A with it unknown mass placed on it, is motionless. After the collision Cart B + Cart A...
