Block 1, of mass m1 = 3.70 kg , moves along a frictionless air track with speed v1 = 23.0 m/s . It collides with block 2, of mass m2 = 23.0 kg , which was initially at rest. The blocks stick together after the collision. (a) Find the magnitude pi of the total initial momentum of the two-block system. (b) Find vf, the magnitude of the final velocity of the two-block system. (c) What is the change ΔK=Kfinal−Kinitial in the two-block system's kinetic energy due to the collision?

On a frictionless horizontal air table, puck A (with mass 0.254 kg ) is moving toward puck B (with mass 0.365 kg), which is initially at rest. After the collision, puck A has velocity 0.116 m/s to the left, and puck B has velocity 0.646 m/s to the right. a) What was the speed vAi of puck A before the collision? b) Calculate ΔK, the change in the total kinetic energy of the system that occurs during the collision.

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at voi = 3.00 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 0 = 35.0° with the horizontal axis while the green disk makes an angle of o 55.0° with this axis as in Figure b. Determine the speed of each disk after the collision. Vof = m/s Vaf = m/s After the collision Before the collision Need Help? Watch It Read It

A 0.20 kg object is gliding to the right on a frictionless, horizontal air track with a speed of 2.00 m/s. It has a head-on collision with a 0.40 kg object that is gliding to the left with a speed of 0.75 m/s. Find the final velocity (magnitude and direction) of each glider if the collision is elastic.
