Question

- Find the velocity of the center of mass both before and after the collision. (These numbers should be nearly identical.) Show your work and show the two values side by side.

- Using the initial COM velocity you found in step 1 above:
verify that in the COM frame, the
*speed*of each cart is the same before and after the collision. That is that the magnitude of velocity 1 is the same before and after the collision, and the magnitude of velocity 2 is the same before and after the collision: v_{01}^{*}= -v_{1}^{*}and v_{02}^{*}= -v_{2}^{*}

3.Verify that the closing speed before the collision has the same magnitude as the retreat speed after the collision

+v10 = 4.38 m/s, and cart 2 has mass 819 g. Assume the track is
frictionless, and after the "elastic" collision cart 1 is moving at
v1 = -2.429 m/s and cart 2 is moving at v2 = 1.786 m/s. a) What
percentage of the original energy was lost in this collision? % b)

external forces?...

Cart 1, with m1= 5.8 kg, is moving on a frictionless linear air
track at an initial speed of 1.8 m/s. It undergoes an elastic
collision with an initially stationary cart 2, with m2, an unknown

direction at 0.7 m/s. 1) The horizontal component of the momentum
is conserved for cart 1. cart 2. the system of cart 1 and cart 2.
Momentum is not conserved for any of these...

An object of mass M moving at speed v0 has a direct elastic
collision with a second object of mass m that is at rest. Using the
energy and momentum conservation principles, it can be shown that
the final velocity of the object of mass M is v=(M−m)v0/(M+m).

Two cars of equal mass are traveling as shown in the figure
below just before undergoing a collision. Before the collision, one
of the cars has a speed of 17 m/s along +x, and the other has a

together after the collision. What are the magnitude and direction
of their final velocity?
