Energy, work, power unit 3 question

AI Thread Summary
The discussion revolves around a physics problem involving a man pulling a box with a force of 65N and an acceleration of 1.27 m/s². The goal is to determine the angle theta at which the force is applied, assuming friction is negligible. Key equations mentioned include Fnet=ma and Fnet=Fcos(theta), which are essential for solving the problem. Participants suggest using components of force and acceleration to find the solution. The thread emphasizes the need for clarity in applying these concepts to arrive at the correct angle.

Homework Statement



The diagram provided shows a man pulling a box across the floor. Assume that the force of the friction can be ignored and that the acceleration of the box is 1.27 m/s. Find the angle to the horizontal that the man must pull.

65N figure located on the rope the person is pulling
15 kg is the mass of the box
Angle is theta so basically the variable that needs to be found


Homework Equations


Fnet=ma
Fnet=Fcos[theta]
I believe these equations are involved


The Attempt at a Solution


Not sure how to put this altogether and solve. Dont have an answer sheet so i can't check the answer. :(

Hi Dcpc10! Welcome to PF! :wink:

Use components of force and acceleration in the horizontal direction …

what do you get? :smile:​
 

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...
