a curling rock with a mass 22 kg is traveling 0 degrees at 3m/s and collides with a stationary object with the same mass the collision is a glancing one and the struck roce is moving 1m/s at 65 degrees what is the velocity after the collision

The final momentum is 22*3 kg m/s

you are given one objects mass, velocity after collision.

for that object, zero deg momentum is 22*1*cos65

subtract that from the initial momentum at zero, and you have the zero deg momentum of rock 2.

Now the other direction>

at 90 deg, the moving rock momentum is 22*1*sin65

the other rock must be moving then at momentum 22^1*sin(180+65)

now, you can find the velocity and direction of the original rock after collision, you have two components at ninety degrees.
