I don't understand. I need to isolate v2fsinθ2 and v2fcosθ2 in EACH momentum equation, then substitute into the energy equation? Am I isolating just v2f or do I include the trig functions in my isolation? And how am I supposed to substitute? Do I substitute the result from isolating v2fsinθ2 and...

So are you saying my professor wrote the problem wrong? That the problem is unsolvable if the angle is greater than 30°? I don't see why the angle must be 30° or lower... Thanks for the reply by the way. :smile:

Homework Statement Let a particle of mass 2M have an initial velocity of v0i (the i merely indicating it is traveling on the x axis) and undergo an elastic glancing collision with a particle of mass M initially at rest. After the collision, the M particle moves off at an angle of 45° above the...
