#### Solution Preview

USE OF EQUATION OF MOTION IN TERMS OF RADIAL AND TRANSVERSE DIRECTIONS

a.) Because along the radial direction:

Tension in the cord:

T = m*r*Q_dot^2

Read Q as theta.

Q_dot == theta dot = d(Q)/dt = 10t rad/s

The cord will break when T = 18 N

=> ...

#### Solution Summary

This solution describes in 176 words how to find the acceleration and force through using the equation of motion, tension, and time.
