PHYSICS ROTATION PROBLEMS-I have answers just need help explaining

Question

1. You are riding a Merry-go-round that rotates at 5.0 rpm. If your horse is located 4.0 m from the axis of rotation, how fast are you going in m/s? (answer: 2.1 m/s)
2. A chicken is running in a circular path with an angular speed of 0.95 rad/s. How long does it take the chicken to complete one revolution. (answer: 6.6 s)

Answer 1

Use V = R*w

V= Linear Speed

R = Distance from Axis of Rotation

w = Angular speed

w = 2*Pai* Frequency of rotation in cycle per sec = 2*3.14 *(5/60)

frequency = 5/60 rounds /sec

V = 2.09 m/s
