Answer 1

The angular velocity of the propeller is 136.1 rad/s; linear velocity is 153.1 m/s; centripetal acceleration 20835.2 m/s² and 2123.8 g.

What is the angular velocity of the propeller?

The angular velocity of the propeller in rad/s is given as follows:

• 1 rev/m = 2π/60 rad/s.

1300 rev/min = 1300 * 2π/60 = 136.1 rad/s.

b. The linear velocity, v = radius * angular velocity

Linear velocity, v = 2.25/2 * 136.1

v = 153.1 m/s

c. Centripetal acceleration, $a = \frac{v^{2}}{r}$

$a = \frac{(153.1)^{2}}{1.125} = 20835.2\:ms^{2}$

Centripetal acceleration in terms of g; $g = \frac{20835.2}{9.81} = 2123.8 g$

Therefore, the angular velocity of the propeller is 136.1 rad/s; linear velocity is 153.1 m/s; centripetal acceleration 20835.2 m/s² and 2123.8 g.
