How Far Will the Glass Travel After Falling Off the Bar?

AI Thread Summary
A bartender slides a glass of beer with an initial velocity of 2 m/s down a 3 m bar, facing a kinetic friction coefficient of 0.05. The frictional force calculated is 0.25 N, affecting the glass's motion before it falls. The total distance traveled by the glass when it hits the ground is expressed as (3 + x), where x is the distance from the bar to the impact point. To solve the problem, one must determine the final velocity at the edge of the bar and apply projectile motion equations. Understanding these dynamics is crucial for accurately predicting how far the glass will travel after falling.

Kinematics/Dynamic Question!

Homework Statement



A bartender slides a glass of beer down a bar with an initial velocity of 2m/s. The coefficient of kinetic friction of the bar is 0.05 and the length of the bar is 3m and the height of the bar is 1m. The mass of the beer is 0.5kg. How far from the bar will the glass hit the ground?

Homework Equations

Not sure which equation to use.

The Attempt at a Solution



I tried to find out the frictional force and its 0.25N after drawing a free body diagram for the glass of beer. I named the distance we have to find from the bar when the glass hits the ground x. Therefore, the total distance traveled by the bar will be (3+x).

I'm stuck after that.

Thank you for anyone who can help me!

Dynamic
You have initial velocity.
There is a force that changes this velocity.
Find the final velocity at the edge of the table.

Kinematic
Use projectile equations.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging 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...
