Net Force on 5kg Suitcase and Applied Force Calculation

AI Thread Summary
The net force acting on a 5kg suitcase, when lifted with a force of 60N, is calculated by subtracting the weight of the suitcase (49N) from the applied force. This results in a net force of 11N directed upwards. Using the equation ma, the acceleration of the suitcase is determined to be 2.2 m/s² in the upward direction. The applied force is 60N, while the weight of the suitcase due to gravity is 49N. Overall, the suitcase experiences a net upward force and acceleration when lifted.

Homework Statement


What is the net force acting on a 5kg suitcase when picked up with 60N of force? what is the applied force? What is the acceleration of the suitcase?



Homework Equations


ma=?



The Attempt at a Solution


I'm not even sure on how to start the equation all I know is ma=
 
Physics news on Phys.org
The force upwards is 60N, the force downward is simply (5kg)(9.8m/s^2), or weight times gravity to give you force, since gravity is acting on the suitcase.

So, the upward force of 60N minus the downward force of 49N (from 5*9.8), and you get 11N in the positive upward direction.

ma = 11N

a = 11N / 5kg = 2.2 m/s^2 (in the upwards positive direction)
 

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...
