Radial and Tangential Acceleration Question

AI Thread Summary
The discussion revolves around calculating the tangential component of acceleration for a ball swinging in a vertical circle. The ball, attached to a 0.5 m string, is at a 20-degree angle with a speed of 1.5 m/s. Participants are seeking assistance with the velocity function and understanding the forces acting on the ball, including the tangential force. The main focus is on determining how to find the tangential acceleration at that specific moment. Clarification on these concepts is essential for solving the problem.

A ball tied to the end of a string 0.5 m in length swings in a vertical circle under the influence of gravity. When the string makes an angle of 20 degrees with the vertical, the ball has a speed of 1.5 m/s. Find the tangential component of acceleration at this instant. Help!




Tangential Acceleration = dv/dt


I could figure this out but I can't figure out the velocity function. HELP me please!

What forces act on the ball? What tangential force acts on the ball?
 

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...
