Homework Statement
There are 2 pucks with different masses. Puck 2 is initially at rest, and Puck 1 is moving horizontally in the positive x direction. The collision has sent the pucks off at angles θ1 and θ2 measured relative to the x-axis, along which Puck 1 initially traveled. Assume momentum is conserved for this collision and
write the conservation of momentum expression for each of the two dimensions.
Homework Equations
The Attempt at a Solution
I list out my variables.
mass
m1, m2
velocities
vix1
viy1=0
vfx1=vf1*cos(θ1)
vfy1=vf1*sin(θ1)
vix2=0
viy2=0
vfx2=vf2*cos(θ2)
vfy2=vf2*sin(θ2)
Here i set up the problem.
Pfsysx=Pisysx
m1(vf1*cos(θ1)) +m2(vf2*cos(θ2)) = m1(vix1)
Pfsysy=Pisysy
m1(vf1*sin(θ1)) +m2(vf2*sin(θ2)) = 0
does this seem right? can i go any further?
