At points 25 cm from the center, the wheels move at a speed of 10 m / s. What is the period of rotation of the wheel?

Initial data: R (distance from the center of the wheel to the given points) = 25 cm = 0.25 m; V (linear speed of movement of points) = 10 m / s.

To calculate the rotation period of this wheel, use the formula:

T = 2ΠR / V.

Let’s do the calculation:

T = 2 * 3.14 * 0.25 / 10 = 0.157 s.

Answer: The period of rotation of this wheel is 0.157 s.
