Homework Statement
This is collision in 2D problem. I already did most of the work except I'm stuck on the trigonometry and algebra for solving for the final velocity of object a.
I will put the problem here just in case someone wants to show me a better way for getting to the answer.
Collision between two pucks. Puck "a" has mass = 0.025kg Velocity of "a" = +5.5m/s
along x-axis "a" makes collision with puck "b" which has mass = 0.050kg and "b" starts at rest. Collision is not head on. So, after collision puck "a" flies apart from "b" at angle 65° and puck "b" flies off at angle 37°
Homework Equations
I am trying to solve for Vfa;
Ma*Voa = Ma*Vfa(cos65) + [Ma*Vfa(sin65)/(sin37)](cos37)
Ma = X
Voa = Y
Vfa = Z
XY = XZ(cos65) + [ XZ(sin65)/(sin37)](cos37) solve for Z
Hopefully that's better.
The solutions in textbook managed to solve for Vfa or Z like this:
Z = Y/[cos65 + (sin65/tan37)]
My question how to get Z by itself and where did (sin65/tan37) come from?
