Question

Тело массой 500 г движется с постоянной скоростью 20 м/с по окружности радиусом 40 см. Определить центробежную силу, действующую на тело​

Answer 1

Ответ:

500 H

Объяснение:

m=0.5 кг    v=20 м/с     R=0.4 м    F=?

===

F=m*v²/R=0.5*20²/0.4=500 H

Answer 2

Problem Analysis

We are given the mass of an object, its constant velocity, and the radius of the circular path it is moving along. We need to determine the centripetal force acting on the object.

Solution

The centripetal force acting on an object moving in a circular path is given by the formula:

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 - R is the radius of the circular path

Let's substitute the given values into the formula to calculate the centripetal force.

Calculation

Given: - Mass (m) = 500 g = 0.5 kg - Velocity (v) = 20 m/s - Radius (R) = 40 cm = 0.4 m

Using the formula F = (m * v^2) / R, we can calculate the centripetal force:

F = (0.5 * 20^2) / 0.4

Simplifying the equation:

F = (0.5 * 400) / 0.4

F = 200 / 0.4

F = 500 N

Therefore, the centripetal force acting on the object is 500 N.

Answer

The centripetal force acting on the object with a mass of 500 g, moving with a constant velocity of 20 m/s along a circular path with a radius of 40 cm, is 500 N.
