## Homework Statement

A curious child finds a rope hanging vertically from the ceiling of a large storage hangar. The child grabs the rope and starts running in a circle. The length of the rope is 14.0m. When the child runs in a circle of radius 7.0m, the child is about to lose contact with the floor. How fast is the child running at that time?

## Homework Equations

Fc=mv^2/r

a=v^2/r

## The Attempt at a Solution

I tried finding the Fx of the length so 14cos(78.46)

I found the angle by doing SOH CAH TOA since the rope length and radius are in an angle

Anyways i heard v=radical rg but idk if its relevant

Then I got stuck
