R = 5 m.
T = 10 s.
V -?
To determine the speed of movement V, it is necessary to divide the entire path S traveled by the time of its passage t: V = S / t.
The period of rotation T is the time of one complete revolution. During the time t = T, the body passes the path S = 2 * п * R.
V = 2 * п* R / T.
V = 2 * 3.14 * 5 m / 10 s = 3.14 m / s.
Answer: the body is moving at a speed of V = 3.14 m / s.
