AI Thread Summary
Wind on Venus, despite being slow, can influence the maximum height of a pendulum by exerting a constant force on it. The pendulum's height can be analyzed by considering the gravitational acceleration on Venus and the forces acting on the pendulum when released. Calculating the maximum height involves determining the equilibrium position and assessing the pendulum's motion under the influence of both gravity and wind. The discussion also raises questions about whether the equilibrium height can exceed the length of the pendulum. Ultimately, understanding these dynamics is crucial for accurately determining the pendulum's behavior in Venus's unique atmospheric conditions.

Homework Statement



Imagine a space station has been built on Venus, and a pendulum is taken outside to determine the acceleration of gravity. The pendulum is a ball having mass m is connected by a strong string of length L to a pivot point and held in place in a vertical position. A wind exerting constant force of magnitude F is blowing from left to right.

Venus has an extremely dense atmosphere, which consists mainly of carbon dioxide and a small amount of nitrogen. The winds near the surface of Venus are much slower than that on Earth. They actually move at only a few kilometers per hour (generally less than 2 m/s and with an average of 0.3 to 1.0 m/s), but due to the high density of the atmosphere at the surface, this is still enough to transport dust and small stones across the surface.

(a) If the ball is released from rest, what is the maximum height H reached by the ball, as measured from its initial height? Check if your result is valid both for cases when 0 H L, and for L H 2L.
(b) Compute the value of H using the values m = 2.00 kg, L = 2.00 m, and F = 14.7 N. The gravitational acceleration on Venus is measured to be m/s2
(c) Using these same values, determine the equilibrium height of the ball.
(d) Could the equilibrium height ever be larger than L? Explain.

The Attempt at a Solution


I honestly have no idea where to even start this. My only thought was you take the maximum velocity that the wind could be and somehow use this to calculate height?

Identify the forces acting on the ball in its defected position. From that find the angle of deflection with vertical by resolving the forces along x and y axis.
 
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...
