AI Thread Summary
Friction significantly impacts the speed of a block on a sloped ramp, as demonstrated by a scenario involving a 2.0 kg wood block launched at 10 m/s up a 30-degree incline with a kinetic friction coefficient of 0.200. The discussion clarifies that the final velocity refers to the speed of the block as it returns to its starting point after sliding back down. A participant initially misunderstood the question regarding final versus initial velocity but later confirmed it was a straightforward calculation. Ultimately, the problem was resolved through basic multiplication. Understanding the effects of friction is crucial for accurately determining the block's speed on the ramp.

im having a lot of trouble with this one also:

A 2.0 kg wood block is launched up a wooden ramp that is inclined at a 30 degree angle. The block's initial speed is 10m/s. The coefficient of kinetic friction of wood on wood is .200.
What speed does it have when it slides back down to its starting point?

PROBLem is solved folks, thanks for the help HallsofIvy

is the second question asking for the final velocity or the initial?

Well, you said "What speed does it have when it slides back down to its starting point?" It slides up the slope, then back down. Assuming that by "final velocity" you mean its velocity as it passes that initial point the second time, yes, that is what is asked.
 
arg that's what i thought, but i got that answer wrong

EDIT: it was a simple multiplication problem

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...
