Two objects, both with a mass of 1.91 kg are sliding across a horizontal, frictionless surface toward each other. If mass 1 has an initial velocity of 3.5 m/s i  and mass 2 has an initial velocity of -2.46 m/s i, what is the change in total kinetic energy if they undergo a perfectly inelastic collision? Assume that total momentum is conserved.

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 13 kg mass traveling at 4 m/s meets and collides with a 3 kg mass traveling at 6 m/s in the opposite direction. The objects bounce off of each other. Take the rightward direction to be positive. Name the type of collision (elastic or inelastic). Then find the final velocities of both objects.

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 29 m/s. The masses of the two objects are 2.8 and 8.8 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is the one moving initially and the case (b) when the small-mass object is the one moving initially.
