Homework Statement


A block with mass m = 24.6 kg slides down an inclined plane of slope angle 38.4 o with a constant velocity. It is then projected up the same plane with an initial speed 4.90 m/s. How far up the incline will the block move before coming to rest?

The Attempt at a Solution



I honestly have little idea what to do on this problem. If someone could give me some leading questions or an applicable equation it'd be much appreciated.

Why constant velocity?

Hi ohhi! (Or is it Yippee-i ohhi?)

At first I thought you'd got the question wrong, because how could it possibly slide down with a constant velocity?

Then I saw the light! Sometimes one has to be able to see the difference between a problem and a solution!

So: Hint: How can it slide down with a constant velocity? :smile:

Yeah, I actually realized and got that. I just came back to say I found the answer. Thanks.
 
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'
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...
