Box attached to end of a string, what is the max velocity?

AI Thread Summary
The discussion revolves around calculating the maximum speed of a 0.60 kg mass attached to a 1.7 m string, which will break if the tension exceeds 60 N. Participants emphasize the importance of applying Newton's second law and centripetal force concepts to solve the problem. A free body diagram is suggested as a useful tool for visualizing the forces acting on the mass. The conversation encourages seeking clarification on specific concepts if needed. Ultimately, understanding these principles is crucial for determining the maximum velocity before the string breaks.

Homework Statement


a 0.60 kg mass is attached to one end of a 1.7 m string. The string will break if its tension exceeds 60 N. The mass is whirled in a horizontal circle on a frictionless tabletop, such that the other end of the string remains fixed at the axis of rotation. What is the maximum speed of the mass before the string breaks? you may treat the mass as a point mass, assume that the string is ideal, and neglect friction.

A.) 4.6 m/s
B.) 7.8 m/s
C.) 13 m/s
D.) 21 m/s
E.) 170 m/s

The Attempt at a Solution


[/B]I don't know where to begin
 
Physics news on Phys.org
Are you familiar with Newton second laws?
What about centripetal force?
Can you draw a free body diagram of the mass?
If the answer to any of these is no, refer to your textbook or google then ask specific question on anything you don't understand.
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
