Simple Pendulum Homework: Amplitude of 25 cm/s Push

AI Thread Summary
The discussion focuses on a physics homework problem involving a pendulum with a 500 g bob and a 75 cm rod, where the bob is pushed to a speed of 25 cm/s. Participants emphasize the importance of providing an initial attempt at solving the problem to facilitate assistance. The calculation of the amplitude of the pendulum's oscillation in degrees is the main objective, with the assumption of neglecting damping. The conversation highlights the necessity of understanding the principles of pendulum motion to arrive at the correct answer. Engaging with the problem through an initial attempt is crucial for effective learning and support.

Homework Statement


A pendulum consists of a 500 g bob at the end of a massless 75 cm rod.
(a) While it is hanging vertically down, the bob is given a push that starts it moving at 25
cm/s. What is the amplitude of the resulting oscillation in degrees? You may neglect
damping.

Okays, first off an attempt is at least required before we can help you, and most importantly without the attempt we can see what you're doing wrong, or what you may have misunderstood.
 

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'

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...
