A 0.50 kg toy is attached to the end of a 1.0 m very light string. The toy is whirled in a horizontal circular path on a frictionless tabletop. If the maximum tension that the string can withstand without breaking is 350 N. What is the maximum speed the mass can have without breaking the string?

Respuesta :

Answer:

The maximum speed will be 26.475 m/sec

Explanation:

We have given mass of the toy m = 0.50 kg

radius of the light string r = 1 m

Tension on the string T = 350 N

We have to find the maximum speed without breaking the string  

For without breaking the string tension must be equal to the centripetal force

So [tex]T=\frac{mv^2}{r}[/tex]

So [tex]350=\frac{0.5\times v^2}{1}[/tex]

[tex]v^2=700[/tex]

v = 26.475 m /sec

So the maximum speed will be 26.475 m/sec
