Find the centripetal acceleration of the yoyo

AI Thread Summary
To find the centripetal acceleration of a yoyo swinging in a horizontal circle at a 30-degree angle, the tension in the cord must be analyzed. The horizontal component of the tension provides the centripetal force, while the vertical component balances the weight of the yoyo. By applying Newton's second law, the tension can be calculated from the gravitational force. Once the tension is known, the centripetal force and acceleration can be determined. This method effectively solves the problem of calculating centripetal acceleration for the yoyo.

hey evr1...i have been trying to do this quest...but somehow can't get it...any help is really appreciated..thnx

a child swings a yoyo of weight mg in a horizontal circle such tht the cord makes an angle of 30 with the vertical. find the centripetal acceleration of the yoyo. (g=10m/s/s)?

it wuld be gr8 if sum1 showd the steps to this problem

Since the yoyo is in constant motion (no acceleration), then the horizontal part of the ropes tension (T*sin(angle)) equals the centripetal force. with the force you can find the acceleration (2 law). You also know that the vertical part of the tension (T*cos(angle)) equals the downward force of gravity (mg). Use that to find the tension, and use the tension to find the centripetal force and acceleration.
 
hey..thnx a lot...u saved ma life..thnx
 

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'

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...
