The blades of an aeroplane propeller are 2 m long and rotate at 300 rpm. Calculate (i) the frequency, (ii) period of rotation, (iii) the angular velocity, (iv) linear velocity of point 0.5 m from the top of the blades.

Explanation

To solve the problem step by step, we will calculate each of the required quantities: frequency, period of rotation, angular velocity, and linear velocity.

### Given Data:
- Length of the blades (L) = 2 m
- Rotation speed = 300 rpm
- Distance from the top of the blades (d) = 0.5 m

### Step 1: Calculate the Frequency
