Question

Под действием силы,модуль которой равен 48 H,тело массой 3 кг движется по окружности с постоянной по модулю скоростью,равной 20 м/с.чему равен радиус окружности?

Answer 1

3 кг переведи в г и раздели то что получиться на 48 Н

Answer 2

Calculation of the Radius of the Circle

To find the radius of the circle, we can use the formula for centripetal force:

F = m * v^2 / R

where: - F is the centripetal force, - m is the mass of the object, - v is the velocity of the object, and - R is the radius of the circle.

In this case, we are given: - F = 48 H (force), - m = 3 kg (mass), and - v = 20 m/s (velocity).

Substituting these values into the formula, we can solve for R:

48 = 3 * 20^2 / R

Simplifying the equation:

48 = 3 * 400 / R

48 = 1200 / R

Cross-multiplying:

48R = 1200

Dividing both sides by 48:

R = 1200 / 48

R = 25

Therefore, the radius of the circle is 25 meters.
