2. Two identical objects A and B of mass M move on a one-dimensional, horizontal air track. Object B
initially moves to the right with speed vo. Object A initially moves to the right with speed 3vo, so that it
collides with object B. Friction is negligible. Express your answers to the following in terms of M and vo.
a. Determine the total momentum of the system of the two objects.
b. A student predicts that the collision will be totally inelastic (the objects stick together on collision).
Assuming this is true, determine the following for the two objects immediately after the collision.
i. The speed

Transcribed Image Text:ii. The direction of motion (left or right)
(continued on next page)
When the experiment is performed, the student is surprised to observe that the objects separate after
the collision and that object B subsequently moves to the right with a speed 2.5vo.
c. Determine the following for object A immediately after the collision.
i. The speed
ii. The direction of motion (left or right)
d. Determine the kinetic energy dissipated in the actual experiment.
