Question

Велосипедист двигается со скоростью 18м/с. Центростремительное ускорение точек колеса наиболее удаленного от его все равно 220 м/С².Найдите радиус колеса велосипеда ​

Answer 1

Ответ: 1,47

Объяснение:

a (центрострем) = V²/r

Соответственно r=V²/a= 324/220~1,47

Answer 2

Calculation of the Radius of the Bicycle Wheel

To find the radius of the bicycle wheel, we can use the formula for centripetal acceleration:

Centripetal acceleration (a) = (v^2) / r

Where: - v is the velocity of the bicycle (18 m/s) - r is the radius of the bicycle wheel (to be determined)

We are given that the centripetal acceleration of the points on the wheel furthest from its center is 220 m/s². Using this information, we can set up the equation:

220 = (18^2) / r

To solve for r, we can rearrange the equation:

r = (18^2) / 220

Now, let's calculate the value of r:

r = (18^2) / 220 = 324 / 220 = 1.4727 meters

Therefore, the radius of the bicycle wheel is approximately 1.4727 meters.
