Question

Радиус ветроколеса составляет 2 м. Частота его вращения 0,5 с. Чему равна линейная скорость крайних точек колеса?

Answer 1

R=2 м
υ= 0,5 с^-1
v-? 
 v=ωR=2πυR.
v=6,28*0,5*2=1,64 м/с.

Answer 2

Calculation of Linear Velocity of the Wheel

To calculate the linear velocity of the outermost points of the wheel, we can use the formula:

Linear Velocity = Radius × Angular Velocity

Given that the radius of the wheel is 2 m and the angular velocity is 0.5 s, we can substitute these values into the formula:

Linear Velocity = 2 m × 0.5 s

Calculating this expression, we find that the linear velocity of the outermost points of the wheel is 1 m/s.
