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:
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
