Question

Точка вращается по окружности радиусом 2 м с периодом 10 с. определить линейную скорость

Answer 1

V=2пR/T=2*3,14*2/10=2,5 м/c

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 - π is a mathematical constant approximately equal to 3.14159 - r is the radius of the circle - T is the period of rotation

In this case, the radius of the circle is given as 2 m and the period of rotation is given as 10 s.

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

v = (2π * 2) / 10

Let's calculate this:

v = (2 * 3.14159 * 2) / 10

v ≈ 1.256637 m/s

Therefore, the linear velocity of the point rotating in a circle with a radius of 2 m and a period of 10 s is approximately 1.256637 m/s.
