Cart A, with a mass of 0.2 kg, travels on a horizontal air track at 3 m/s and hits cart B, which has a mass of 0.4 kg and is initially at rest. After the collision the center of mass of the two cart system has a speed in m/s of:

Step 1
The total momentum before the collision is the sum of the momenta of the two carts. The momentum of an object is given by the product of its mass and its velocity. So, the momentum of cart A before the collision is (0.2 kg) * (3 m/s) = 0.6 kg*m/s. The momentum Show more…

An air-track cart with mass m1 = 0.30 kg and initial speed v0 = 0.80 m/s collides with and sticks to a second cart that is at rest initially. If the mass of the second cart is m2 = 0.46 kg, how much kinetic energy is lost as a result of the collision?

A cart with mass 0.340 kg moving on a frictionless linear air track at 1.2 m/s strikes a second cart of unknown mass at rest. The collision between the two carts is elastic. After the collision, the first cart continues in its original direction at 0.66 m/s. a) What is the mass of the second cart? b) What is the velocity of the second cart after impact?

Calculate A cart of mass $m=0.12 \mathrm{~kg}$ moves with a speed $v=0.45 \mathrm{~m} / \mathrm{s}$ on a frictionless air track and collides with an identical cart that is stationary. The carts stick together after the collision. What are (a) the initial kinetic energy and (b) the final kinetic energy of the system?
