How Do You Calculate the Initial Height of a Block on a Frictionless Ramp?

AI Thread Summary
To calculate the initial height of a block on a frictionless ramp, additional information is necessary, such as the block's velocity or other relevant parameters. The problem currently lacks sufficient details to derive a numerical value, suggesting that the solution may need to be expressed in terms of variables. The ramp's height of 2.6 meters is noted, but without further data, a specific calculation cannot be performed. Participants in the discussion emphasize the importance of having complete information to solve the problem accurately. Clarifying these details will lead to a more precise answer.

I need help!

I have a 426g block on a frictionless ramp with initial height, h. The ramp curves, where the height is 2.6 meters before it flies off. I need to know the initial height, can someone please help? :smile:

can you give us more info about this . Or is that all you know.
 
There must be some more information in this problem, unless if your teacher just wants you to express your answer in variables. Perhaps a velocity would help us out?
 
some more information relevant to the problem must be given to solve for a numerical value otherwise your solution will be a general solution involving variables...
 
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...
