    Inclined Mass
AI Thread Summary
To determine Brisket's mass while moving down a frictionless inclined plane at a 24° angle, the applied force of 1008N must be balanced against the gravitational component acting down the ramp. The correct approach involves using the equation mg*sin(24°) - FR = ma, where 'm' is the mass, 'g' is the acceleration due to gravity, and 'a' is the acceleration of 0.29m/s². A free body diagram is essential for visualizing the forces acting on Brisket. The initial calculation of mass using Fn = mg cos(24°) is incorrect due to not accounting for the direction of acceleration. Properly applying the forces will yield the correct mass of Brisket.

applied all the force FR=1008N that I could to the (massless, unstretchable) rope in an effort to pull Brisket into the trailer, up the ramp that formed an angle of 24.0° with the ground. Brisket moved down the ramp with an acceleration of magnitude 0.29m/s2. With this information, and assuming the ramp is frictionless, what is Brisket's mass (in kg)?

What i have done so far is Fn = mg cos (angle) and that is 1008/ 9.8cos 24(degrees)= 112.59 kg but it is not correct can anyone direct me into the right direction

Much appreciated

You're trying to pull the object UP the ramp, but it's moving DOWN. Draw a free body diagram!
 
The equation should be
mg*sin(24)(downward force) - FR = ma
 

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...
