    Force Swing
AI Thread Summary
Tarzan, weighing 820N, swings from a 20.0m vine at a 22.0° angle with a tension of 760N in the vine immediately after stepping off the cliff. To determine the force acting on him from the vine, one must analyze the forces involved, including gravitational force and tension. The discussion suggests using the equation for centripetal force, mv²/r, to solve the problem. The inquiry hints at potential complexities in the calculations, indicating it may not be straightforward. Understanding the balance of forces is crucial for accurately determining the resultant force on Tarzan.

Hi, I have a question regarding forces and motion that I'm not sure on how to solve. I was wondering if anyone here could please show me. Thank you.

Question: Tarzan weighs 820N and swings from a cliff at the end of a 20.0m vine that hangs from a high tree limb and initially makes an angle of 22.0 degrees with the vertical. Assume that an x-axis extends horizontally away from the cliff edge and a y-axis extends upward. Immediately after Tarzan steps off the cliff, the tension in the vine is 760N. Just then, what is the force on him from the vine.

Try summing up the forces and equate to mv^2/r

Sounds like a trick question to me. :wink:
 

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. 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...
