AI Thread Summary
The problem involves an 11.4-kg block on a frictionless incline of 47°. The net force acting on the block after release can be calculated using gravitational force components. The block's acceleration can be determined using Newton's second law, and the time to reach a speed of 9 m/s can be found using kinematic equations. Participants in the discussion are encouraged to share their solutions to identify any errors in calculations. The focus remains on solving the physics problem accurately.

[SOLVED] Block on an incline

A 11.4-kg block is released from rest on a frictionless track inclined at an angle of 47°. (a) What is the net force on the block after it is released? (b) What is the acceleration of the block? (c) If the block is released from rest, how long will it take for the block to attain a speed of 9 m/s?

I have been working on this problem but for some reason I must have an error somewhere, can anyone show me the correct answers.

If you show us your solution we can maybe find the error.
 

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...
