Two carts are on an air track (no friction). The first cart, with a mass of...
Two carts are sitting on air track (frictionless surface). Assume cart A has mass of .50 kg, cart B has mass of 1.0 kg. You push cart A and give it an initial speed of 5.0 m/s toward B which was originally at rest. The two carts stick together and move together. Right after collision, the air is turned off so the two carts slide to a stop due to kinetic friction. Assume the coefficient of kinetic friction is .20....
2. (11 points) Alex is conducting an experiment with carts on an air track. Cart 1 has a mass of 400 grams, cart 2 has a mass of 200 grams, and cart 3 has a mass of 100 grams. The initial velocity of cart 1 is 12 m/s towards the stationary carts. The carts have repelling magnets on their ends so the carts will undergo elastic collisions. a) What will be the final velocity of cart 1 immediately after its...
Two carts on an air track are moving toward each other. One has mass 2.0 kg and velocity -0.90 m/s, and the other has mass 3.0 kg but unknown speed. They collide in a totally inelastic collision, and move with velocity +1.2 m/s after the collision. What was the initial speed of the second cart (in m/s)?
Two carts are rolling to the right along the same level track. Cart 1, with a mass m1 = 3.4 kg, is in the rear, rolling at a speed of 6.2 m/s and catching up to cart 2, which is rolling at a speed of 3.2 m/s. Choose signs carefully; only speeds are given. a) Cart 1 overtakes and collides with cart 2, sticking to it (both have Velcro pads). Afterward, they both continue rolling right, now at a speed...
Two air track carts move along an air track towards each other. Cart A has a mass of 450 g and moves toward the right with a speed of 0.850 m/s. Cart B has a mass of 270 g and moves toward the left with a speed of 1.12 m/s. What is the total momentum of the two-cart system? Give your answer in kg m/s, to three significant firgures. Your Answer: Answer units
A 1.0-kg standard cart collides on a low-friction track with cart A. The standard cart has an initial x component of velocity of +0.40 m/s, and cart A is initially at rest. After the collision the x component of velocity of the standard cart is +0.20 m/s and the x component of velocity of cart A is +0.65 m/s . After the collision, cart A continues to the end of the track and rebounds with its speed unchanged. Before the...
A cart with mass 390 g moving on a frictionless linear air track at an initial speed of 1.3 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the first cart continues in its original direction at 0.95 m/s. (a) What is the mass of the second cart? (b) What is its speed after impact? (c) What is the speed of the two-cart center of mass?
A cart with mass 260 g moving on a frictionless linear air track at an initial speed of 1.4 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the first cart continues in its original direction at 0.84 m/s. (a) What is the mass of the second cart? (b) What is its speed after impact? (c) What is the speed of the two-cart center of mass? (a) Number Units (b) Number Units (c)...
A cart of mass M traveling to the right on a frictionless track with a speed 4v0 collides with another cart of mass 2M traveling to the left with a speed v0. If this collision is perfectly elastic, and carts travel in opposite directions after collision, determine the speeds of the two carts immediately after the collision in terms of M and v0.
