Beer mug across counter direction of mugs velocity

AI Thread Summary
The discussion revolves around a physics problem involving a beer mug sliding off a counter and hitting the floor. The key equation derived for the initial velocity of the mug is Vinitial = d/sqrt(2h/g), where d is the horizontal distance from the counter, h is the height of the counter, and g is the acceleration due to gravity. Participants suggest breaking the motion into components to analyze the velocity direction just before impact. There is also a request for clarification on how to derive the initial velocity equation correctly. Understanding the components of motion is crucial for solving the problem accurately.

Homework Statement


In a local bar, a customer slides an empty beer mug down the counter for a refill. The bartender is momentarily distracted and does not see the mug, which slides off the counter and strikes the floor at distance d from the base of the counter. The height of the counter is h. With what speed did the mug leave the counter? Which I got Vinitial=d/sqrroot(2h/g). Now my question is what was the direction of the mugs velocity just before it hit the floor?

The Attempt at a Solution


Would I have to break something up into components?

Splitting it into perpendicular components seems like an excellent idea :approve:.
 
hmmm, how did you get that equation for Vinitial? i am trying to sift through all these formulas and i just can't seem to get the correct one. :confused:
 
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...
