Answer:

Linear velocity, v = 8.95 m/s

Step-by-step explanation:

It is given that,

Radius of the roller, r = 14.25 cm = 0.1425 m

Angular velocity, \omega=10\ rev/s=62.83\ rad/s

We need to find the linear velocity of the roller. Th linear velocity of the roller is given by :

v=r\times \omega

v=0.1425\times 62.83

v = 8.95 m/s

So, the linear velocity of the roller is 8.95 m/s. Hence, this is the required solution.

A point on the edge of the roller travels the circumference of the roller in 1 revolution, so that its linear velocity is

(10 rev/s) * (2*(14.25 cm)*pi cm/rev) = 285 pi cm/s

or about 895.4 cm/s.

Factor 9s^2 - 36s + 35
Verdich [7]

Split the second term in 9s^2 - 36s + 35 into two terms

9s^2 - 15s - 21s + 35

Factor out common terms in the first two terms, then in the last two terms

3s(3s - 5) - 7(3s - 5)

Factor out the common term 3s - 5

<u>(3s - 5)(3s - 7) </u>
