Question

A rope breaks when the tension reaches 205 N. What is the maximum speed at which it can swing a 0.477 kg mass in a circle of radius 0.725 m?

Answer 1

Answer:

Maximum velocity will be 17.651 m /sec

Explanation:

We have given a rope breaks when tension reaches 205 N

Mass m = 0.477 kg

Radius of the circle r = 0.725 m

Tension in the rope is given by

$T=\frac{mv^2}{r}$

$205=\frac{0.477\times v^2}{0.725}$

$0.477v^2=148.625$

$v^2=311.5828$

v = 17.651 m /sec
