(a) Calculate the speeds and (b) Was the collision elastic? SSM

ANSWER:

Step 1 of 5

(a) In this part of the problem, we are asked to calculate the speeds of two pucks.

A puck of mass moving at approaches an identical puck that is stationary on frictionless ice as shown in the below figure.

The values are

Mass of puck

Initial velocity of puck

Mass of puck

Initial velocity of puck B,

Final velocity of puck at to the original line of motion

Final velocity of puck at to the right of the original line of motion.
