Block pushed up 35degree incline (frictionless)

AI Thread Summary
To determine the acceleration of a block pushed up a 35-degree incline with an applied force of 20N and a mass of 2.0kg, one must analyze the forces acting on the block. The gravitational force acting on the block can be resolved into components, with one component acting down the incline. A free body diagram is recommended to visualize these forces and understand how the gravitational component interacts with the applied force. The net force can then be calculated to find the resulting acceleration using Newton's second law (F=ma). Understanding these concepts is essential for solving the problem effectively.

1. a block is pushed up a 35 degree incline (no friction) by an applied force. If F= 20N and m= 2.0kg, what is the magnitude of the resulting acceleration of the block?



2. not sure?
f=ma



3. don't know where to start. It has been a long time since physics

Welcome to PF.

Start by drawing a free body diagram.

You have gravity of g acting straight down. What component of gravity then is acting down the incline?

And how might this weight component act with respect to the force pushing up the incline?
 

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...
