Inclined plane and kinetic energy

AI Thread Summary
To slide up an inclined plane to a height h without friction, a block of mass m must possess a minimum kinetic energy equal to the gravitational potential energy it gains. This relationship is derived from the principle of energy conservation, where the initial kinetic energy converts into potential energy as the block ascends. Understanding the concepts of energy transformation and the forces at play is crucial for applying the relevant equations effectively. The discussion emphasizes that equations serve as tools to express physical concepts rather than standalone solutions. Grasping these underlying principles is essential for solving problems related to inclined planes and kinetic energy.

if a block of mass m is to slide up an inclined plane to at least a height of h (with no friction), what is the minimum kinetic energy it must have?

no numbers are included...just supposed to know an equation to get the answer.

Use energy Conservation!
Gravitational Potential energy gained= Initial Kinetic Energy
 
Equations are just "tools" of physics. More than "just knowing an equation" what physical concepts are involved here? That should help you think of an equation.
 

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...
