Acceleration given kinetic friction

AI Thread Summary
To find the acceleration of a crate sliding down a ramp inclined at 51.1° with a coefficient of kinetic friction of 1.171, the net force must be calculated using Fnet = mass x acceleration. The mass of the crate is not necessary for determining acceleration, as the forces can be expressed in terms of acceleration alone. A free body diagram can help visualize the forces acting on the crate, including gravitational and frictional forces. The discussion suggests consulting additional resources for further clarification on the calculations. Understanding the relationship between forces and acceleration is key to solving the problem effectively.

1. A crate is sliding down a ramp that is inclined at an angle of 51.1° above the horizontal. The coefficient of kinetic friction between the crate and the ramp surface is 1.171. Find the acceleration of the moving crate.


2. Fnet = mass of object x acceleration


3. Sine I don't have the mass, I'm not sure what to plug into the equation. Can someone walk me through how to solve 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'

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...
