Finding total energy from the top of a hill on a rollercoster?

AI Thread Summary
The total energy of the rollercoaster cart at the specified position is the sum of its gravitational potential energy and kinetic energy. The gravitational potential energy (GPE) is calculated as GPE = m*g*h, resulting in 2695 Joules. The kinetic energy (KE) is determined using KE = 1/2*m*v^2, yielding 687.5 Joules. Adding both energies gives a total energy of 3382.5 Joules for the cart at the height of 5 meters and a velocity of 5 m/s. This calculation encompasses the essential forms of energy involved in the rollercoaster's motion.

would s=d/t be relevant?

The Attempt at a Solution


already calculated
gravitational potential energy: GPE = m*g*h = 2695
kinetic energy: KE = 1/2*m*v^2 = 687.5

You have potential (gravitational, if you will) energy, kinetic energy. I suppose you are not expected to calculate anything more.
 
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...
