Question

A propeller blade, measured from the rotational axis to the tip, has a length of 1.75m. Starting from rest, what is the tangential acceleration of the tip of the blade?

Answer 1

The tangential acceleration of the tip of the propeller blade is 4.50 m/s².

Step-by-step explanation:

To find the tangential acceleration of the tip of the propeller blade, we can use the equation:

Tangential acceleration (at) = Angular acceleration (α) * Radius (r)

Given that the propeller blade starts from rest and rotates with a tangential acceleration of 3.00 m/s² and the tip of the blade is 1.5 m from the axis of rotation, we can substitute the values into the equation:

at = 3.00 m/s² * 1.5 m = 4.50 m/s²

Therefore, the tangential acceleration of the tip of the propeller blade is 4.50
