Question

Please fully show work so that it can be followed in a similar problem.  An object on the end of a string is going around a circle on a horizontal surface that you can assume to be frictionless. The drawing shows the object and string looking down from above the surface.

If the mass of the object is 2.00 kg, the length of the string is 1.4 m, and the string breaks at a tension of 105 N, what is the speed of the object when the string breaks?

Give the answer in m/s to four digits.

If the mass of the object is 2.00 kg, the length of the string is 1.4 m, and the string breaks at a tension of 105 N, what is the speed of the object when the string breaks? Give the answer in m/s to four digits.

Explanation / Answer

Here

Tension = Centripetal Force

So

T = mv^2/L

105 = 2*v^2/1.4

v = 8.573 m/sec
