2 dimensional collision with momentum

AI Thread Summary
The discussion focuses on a two-dimensional collision involving two pucks of different masses, where one puck is initially at rest. The conservation of momentum is applied in both the x and y dimensions, leading to two equations: one for the x-direction and one for the y-direction. The user lists variables for mass and initial/final velocities, correctly setting up the momentum equations. The equations reflect the conservation principles, with momentum before the collision equal to momentum after the collision in both dimensions. The user seeks confirmation on the correctness of their setup and expresses readiness to proceed further.

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?

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
