Answer:
Centripetal force, F = 9.81 N
Explanation:
It is given that,
Mass of the object (yo-yo), m = 0.12 kg
It is whirled around by its string in a circle
Radius of circle, r = 0.44 m
Speed of object, v = 6 m/s
We need to find the required centripetal force in Newtons to keep this yo -yo whirling in a circle. The centripetal force is given by :
[tex]F=\dfrac{mv^2}{r}[/tex]
[tex]F=\dfrac{0.12\ kg\times (6\ m/s)^2}{0.44\ m}[/tex]
F = 9.81 Newton
So, the centripetal force required to keep this yo -yo whirling in a circle is 9.81 N. Hence, this is the required solution.
