Answer:
a) 3.491 in/s
b) 3.333 RPM
c) 0.349 rad/s
Step-by-step explanation:
We know the arc length for a given radius and angle is ...
s = rθ
so the linear speed along the arc is ...
s' = rθ' = (10 in)(20π/180 rad/s) = 10π/9 in/s ≈ 3.491 in/s
__
The rotation rate of 20°/s is an angular velocity of ...
(20°/s)(60s/min)(1 rev/360°) = 3.333 RPM
__
In the first part, we found the angular speed to be π/9 radians/sec. That's about ...
π/9 rad/s ≈ 0.349 rad/s

Answer:
AB = 3.16 units
Step-by-step explanation:
Given:
A(3, -1) and B(6, 0)
To Find:
AB = ?
Solution:
AB = root{(x2 - x1)^2 + (y2 - y1)^2}
AB = root{(6 - 3)^2 + (0 - (-1))^2}
AB = root{(3)^2 + (0 + 1)^2}
AB = root{9 + (1)^2}
AB = root{9 + 1}
AB = root 10
Therefore, AB = 3.16 units
