Solving Inclined Plane Problem: Object Stopping Distance with Friction

AI Thread Summary
To solve the inclined plane problem, the object starts at rest on a frictionless incline and slides down, converting potential energy into kinetic energy. The object then encounters friction on the horizontal surface, which affects its stopping distance. The coefficient of kinetic friction is 0.400, and the incline's angle is 30 degrees. Applying the conservation of energy principle and calculating the forces involved will yield the horizontal distance the object travels before stopping. Understanding these concepts is crucial for determining the stopping distance accurately.

Homework Statement



An Object with a mass of 10.0kg is at rest at the top of a frictionless inclined plane of length 8.00m and an angle of inclination 30.0 with the horizontal. The object is released from this position and it stops at a distance d from the bottom of the inclined plane along a horizontal surface. The coefficient of kinetic friction for the horizontal surface is 0.400. At what horizontal distance from the bottom of the inclined plane will this object stop?

Draw the diagram for initial and final position for the object. Use law of conservation of energy at the top and distace d from the bottom.
 

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...
