The body moves uniformly around a circle with a radius of 50 cm with a linear speed of 7 m / s.

The body moves uniformly around a circle with a radius of 50 cm with a linear speed of 7 m / s. How many revolutions will this body make in 15 minutes (n = 3)

Task data: R (radius of a circle) = 50 cm (in SI R = 0.5 m); V (linear velocity) = 7 m / s; t (duration of body movement) = 15 min (in SI t = 900 s); by assumption, the constant Π = 3.

The number of full body revolutions can be calculated using the formula: n = S / S1 = V * t / (2 * Π * R).

Let’s calculate: n = 7 * 900 / (2 * 3 * 0.5) = 2100 revolutions.

Answer: The body will have time to complete 2100 revolutions in 15 minutes.
