Answer 1

Как-то так получилось)

Answer 2

Calculation of the Speed of the Tip of the Propeller

To determine the speed of the tip of the propeller, we need to calculate the linear velocity of a point on the circumference of the propeller. The linear velocity can be calculated using the formula:

Linear velocity = radius x angular velocity

Given that the radius of the propeller is 1.5 m and the angular velocity is 2000 min^-1, we can calculate the linear velocity as follows:

Linear velocity = 1.5 m x (2000 min^-1) = 3000 m/min

Therefore, the speed of the point at the tip of the propeller is 3000 m/min.

Please note that the unit of measurement used here is meters per minute (m/min).
