Conservation of energy to find horizontal displacement?

AI Thread Summary
To find velocity using conservation of energy, the formula mgh = 0.5mv^2 is applicable when an object falls from rest, converting potential energy into kinetic energy. The velocity calculated from this equation represents the object's speed at the bottom of the height. It's important to note that the specific formula may vary based on the situation being analyzed. Understanding the context of the energy conversion is crucial for accurate calculations. This approach effectively illustrates the relationship between potential and kinetic energy in motion.

Homework Statement



This probably seems really obvious but what formula do you use to find velocity with conservation of energy? Once you find the velocity, is it the velocity of the object at the bottom of the height?

Homework Equations



This is what I'm not sure about. Is it mgh=0.5mv^2?

The formula depends on the situation! The formula you wrote in your last line applies to a situation where an object is falling from rest, converting all of its potential energy into kinetic energy.
 

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
