Question

A point at the end of a propeller has a centripetal acceleration of 532.6 m/s^2.

Answer 1

Answer:

C. 2.3 m

Explanation:

Centripetal acceleration is:

a = v² / r

Given a = 532.6 m/s² and v = 35 m/s:

532.6 m/s² = (35 m/s)² / r

r = 2.3 m

Answer 2

Answer:

r = 2.3 meters

Explanation:

Solution,

Given that,

Centripetal acceleration of the propeller, $a=532.6\ m/s^2$

Velocity of the propeller, v = 35 m/s

To find,

Length of the propeller blade.

Solution,

The centripetal acceleration is given by :

$a=\dfrac{v^2}{r}$

r is the radius of propeller

$r=\dfrac{v^2}{a}$

$r=\dfrac{35^2}{532.6}$

r = 2.3 meters

So, the length of the propeller is 2.3 merets.
