Bungee Jumper Oscillation: Determine Spring Constant

AI Thread Summary
To determine the spring constant of the bungee cord, the oscillation period of the jumper is essential. The jumper, with a mass of 87 kg, oscillates up and down, completing two cycles in 8.5 seconds, indicating a period of 4.25 seconds per cycle. Using the formula for the period of a mass-spring system, T = 2π√(m/k), where T is the period, m is the mass, and k is the spring constant, the spring constant can be calculated. Rearranging the equation to solve for k gives k = (4π²m)/T². This calculation leads to the determination of the bungee cord's spring constant, providing insights into the dynamics of bungee jumping.

A bungee jumper, whose mass is 87 kg, jumps from a tall platform. After reaching his lowest point, he continues to oscillate up and down, reaching the low point two more times in 8.5 s. Ignoring air resistance and assuming that the bungee cord is an ideal spring, determine its spring constant.

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'
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...
