Answer
The linear speed: $2.7\frac{\text{ft}}{\text{s}}$
The angular speed: $0.09\frac{\text{rad}}{\text{s}}$
Work Step by Step
The circumference is: $C=2r\pi=2(30)\pi=60\pi$ ft.
The linear speed: $v=\frac{C}{t}=\frac{60\pi}{70}=2.7\frac{\text{ft}}{\text{s}}$
The angular speed: $\omega=\frac{2\pi}{t}=\frac{2\pi}{70}=0.09\frac{\text{rad}}{\text{s}}$
