Question

Точка вращается по окружности радиусом 0,2м с периодом 2с. Определить линейную скорость.

Answer 1

V=2пR/T = 2* 3,14 * 0,2м/2 с=0,628 м/с

Answer 2

Calculation of Linear Velocity

To determine the linear velocity of a point rotating in a circle, we can use the formula:

Linear velocity (v) = 2πr / T

where: - v is the linear velocity, - r is the radius of the circle, and - T is the period of rotation.

In this case, the radius of the circle is given as 0.2 meters and the period of rotation is given as 2 seconds.

Substituting these values into the formula, we can calculate the linear velocity:

v = (2π * 0.2) / 2

Let's calculate the value.

Using the formula, we find that the linear velocity is 0.628 m/s.
