Question

Период вращения колеса 4сек. Найти скорость вращения крайних точек , удаленных от оси на 2 м ПОЖАЛУЙСТАААА

Answer 1

v=2*π*R/T

R=2

T=4

v=2*3.14*2/4=3.14 м/с

Answer 2

Calculating Wheel Rotation Speed

To calculate the speed of the wheel's outermost points, we can use the formula:

V = 2πr / T

Where: - V = speed of rotation - π (pi) ≈ 3.14 - r = radius of the wheel (in this case, 2 m) - T = time period of rotation (in this case, 4 seconds)

Applying the Formula

Using the given values: - r = 2 m - T = 4 seconds

We can calculate the speed of rotation using the formula:

V = 2 * 3.14 * 2 / 4

Calculation

V = 6.28 / 4

V ≈ 1.57 m/s

So, the speed of rotation of the wheel's outermost points, which are 2 meters away from the axis, is approximately 1.57 m/s.
