Linear & Angular Speed

Section 4.1

Seeking the set up only for parts (a) & (b).

 

[MathLover1]

a.
angular velocity = 5200(2π) rad / min
b.
linear speed= angular speed * radius

 

[nycmathguy]

a.
angular velocity = 5200(2π) rad / min
b.
linear speed= angular speed * radius

For part (a), 5200(2pi) = 1,872,000 rad/minute.

The set up for part (b) is L, where L stands for linear speed.

L = (1,872,000)(rad/min)(29/4 inches)

Yes?
