Change in Velocity Homework Solution

AI Thread Summary
To find the change in velocity of water in the pipe, the entry and exit velocities must be expressed as vectors in xy coordinates. The change in velocity is calculated using the equation V1 - V2, where V1 is the entry velocity and V2 is the exit velocity. The subtraction of these vectors will yield the resultant change in velocity. It is essential to draw the resultant vector to visualize the change. This approach will provide a clear understanding of the velocity change in the system.

Welcome to the PF. I believe that they want you to calculate the change in vector velocity. So express the entry velocity as a vector in xy coordinates, and the exit velocity in xy coordinates. The difference is just the subtraction of the two vectors, carried out with components.

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...
