## Homework Statement

A mass, m, traveling at a speed v, strikes another mass = 2m at rest. After the collision, the first mass, m, is delfected through 45 degrees and has a final speed of v/2.

Find the speed and Direction of the mass 2m after this collision.

## Homework Equations

p =mv

## The Attempt at a Solution

2mfsinT = -mv/2sin 45

mv+2m+ 0 - mv xdr

mv = mv/2cos45+2mfcosT

Anyone help ..
