Finding the Force Applied to a Partner Swinging at 4.25 m/s

AI Thread Summary
To determine the force applied by the man to his partner swinging at 4.25 m/s, the centripetal force formula Fc = (mv^2)/r is used, where m is the weight of the partner (570 N), v is the speed (4.25 m/s), and r is the radius (6.5 m). The calculation results in a force of approximately 1580 N. The user seeks confirmation on the correctness of this logic and calculation. The discussion includes a visual aid to clarify the scenario. Accurate application of the centripetal force equation is essential for solving this problem.

Homework Statement



In the figure the man hanging upside down is holding a partner who weighs 570 N. Assume that the partner moves on a circle that has a radius of 6.50 m. At a swinging speed of 4.25 m/s, what force must the man apply to his partner in the straight-down position?

Homework Equations


Fc=(mv^2)/(t)

The Attempt at a Solution


(570*(4.25)^2) / 6.5

1580 n?

If my logic is wrong, please tell me.

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
