How Do You Calculate Fnet, F2, and Direction of dp/dt in Physics?

AI Thread Summary
To calculate Fnet and F2 in physics, it's essential to understand the forces acting on an object and apply Newton's second law. The direction of dp/dt, which represents momentum change, is determined by the net force acting on the object. In uniform circular motion, an object accelerates toward the center of the circle, indicating that the net force also points inward. Drawing a diagram can help visualize the motion and clarify the reasoning behind the calculations. Understanding these concepts is crucial for solving related physics problems effectively.

Help on Physics Homework??

Some please explain how to get Fnet , F2, and how to find the direction of dp/dt. And the rest of the stuff i got wrong on this homework. anyhelp would be much appreciated.

Why don't you draw a diagram of the motion and tell us the reasoning behind your answers.

Hint: If something moves at constant speed in a circle, in what direction does it accelerate?
 
toward the cent it accelerates? uniform circularmotion?
 

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...
