What Is the Gravitational Potential Energy of a Car on a 10-Degree Hill?

AI Thread Summary
The discussion focuses on calculating the gravitational potential energy of a 1000 kg car at the top of a 10-degree hill. The height of the hill is determined to be approximately 8.816 meters using the formula Height = 50 * Tan 10. The potential energy is then calculated using the formula PE = Mgh, resulting in approximately 86,484.96 joules. The calculations are confirmed as correct by another participant. The thread emphasizes the importance of accurate height and mass in potential energy calculations.

Car has a mass of 1000 kg its at a the top of a 10 degree hill. so if you were to draw a triangle the the base of the triangle would be 50 M in length as well.

a)what is it gravitational potential energy relative to the bottom of the hill?

Height = 50 * Tan 10
= 8.816

Potential energy =Mgh=1000 x 9.81 x 8.816 m=86484.96 J is this right?

looks ok! :smile:

(is something worrying you about it?)
 

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'

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...
