## Homework Statement

A 10kg objects rotates on a point on a wire 3 meters long at the rate of 120 rad/sec without breaking the wire.

**1) What is the numeric value (and units) of the velocity vector**and

**2)what angle does it make with the tangent at any point?**and

**3) What's the minimum tensile strength of wire asumming that is has a 50% safety factor? (Minimum tensile strength of the wire is 1.5 times the working tensile strength)**

Please answer or help me with atleast 1 and 2

## Homework Equations

## The Attempt at a Solution

V=ωr

V=120(3)= 360 m/sec

α=v^2/r

α=129600/3

α= 43200

t= (Vf-Vi)/a

t=(360/43200)

t=.00833 seconds

theta=ω(t)

theta=120(.00833)= 1

please help.
