How do I calculate net force given two force vectors and other parameters?

AI Thread Summary
To calculate net force from two force vectors, it's essential to provide the complete vector value rather than just the individual vectors. The net force can be expressed in vector form, such as F = (11.25N i) + (-22.5N j), or as a magnitude, calculated using F = sqrt((11.25N)^2 + (-22.5N)^2) = 25.16N. Including both the vector and the magnitude in the answer is acceptable and can enhance clarity. The discussion emphasizes the importance of presenting the total vector value for accuracy. Providing comprehensive information in the response is beneficial for understanding net force calculations.

Homework Statement



I am given two two dimensional velocities one final one initial and the time taken for the velocity of the object to change. I am also given the mass and asked to calculate net force.

The calculations are very easy but when asked for the net force am I supposed to give the whole vector value or simply state the two vectors? I am pretty sure I must state the total vector value but I'm not positive.

so either

F= (11.25N i)+(-22.5N j)

or

F= sqrt((11.2Ni)^2+(-22.5Nj)^2)= 25.16

I would go with the vector answer. Nothing wrong with including both if that is possible.
 
Ok thanks
 

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...

Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
