Two objects of different masses slide up an inclined plane.

AI Thread Summary
In the discussion, participants analyze the scenario of two objects of different masses sliding up an inclined plane with equal speeds. The key point is that the heavier object possesses greater kinetic energy due to its mass, which translates into higher potential energy as it ascends. Consequently, the heavier object will rise to a greater height compared to the lightweight object. The consensus is that the heavier object, despite the equal initial speeds, will achieve a higher elevation due to its greater kinetic energy. Thus, the conclusion is that the heavy object rises higher on the incline.

Homework Statement



A lightweight object and a very heavy object are sliding with equal speeds along a level frictionless
surface. They both slide up the same frictionless hill. Which rises to a greater height?
A) The heavy object, because it has greater kinetic energy.
B) The light object, because it has smaller kinetic energy.
C) The lightweight object, because it weighs less.
D) The heavy object, because it weighs more.
E) They both slide to the same height.

Homework Equations



W=-mg


The Attempt at a Solution



I was thinking that the answer is (C) , since the object is light and gravity pulls less on it than the heavy object and it can travel further distance. Any ideas?

Hi megatron99,welcome to PF.
While rising up an inclined plane, the kinetic energy is converted into potential emergy
If both the masses start rising with the same velocity, which has more KE?

The heavier object has more K.E due to more mass , so it has more P.E and i guess more height?
 
Yes.
 

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...
