Question

Винт моторной лодки делает 25 оборотов за 1 секунду.чему равна угловая скорость винта?

Answer 1

Дано N=25 t=1c  w- ?

ω=φ/t=2*π*N/t=6,28*25/1=157 рад/с

Answer 2

Calculating Angular Velocity of the Boat Motor

To calculate the angular velocity of the boat motor, we can use the formula:

Angular Velocity (ω) = (Number of Revolutions) / (Time)

Given that the boat motor makes 25 revolutions in 1 second, we can calculate the angular velocity as follows:

Angular Velocity (ω) = 25 revolutions / 1 second

Result

The angular velocity of the boat motor is 25 radians per second. This means that the boat motor's propeller rotates at a rate of 25 revolutions per second, which corresponds to an angular velocity of 25 radians per second.
