A body weighing 2 kg moves uniformly around the circumference at a speed of 1.5 m / s.

A body weighing 2 kg moves uniformly around the circumference at a speed of 1.5 m / s. rotational speed 3 rad / s. What force is acting on the body.

To find the force acting on a body uniformly moving along a given circle, we will use the formula: F = m * a = m * V ^ 2 / R = m * V ^ 2 / (V / ω) = m * V * ω.
Variable values: m – body weight (m = 2 kg); V – constant speed (V = 1.5 m / s); ω – angular speed of rotation (ω = 3 rad / s).
Let’s do the calculation: F = m * V * ω = 2 * 1.5 * 3 = 9 N.
Answer: A force of 9 N. acts on the body.
