Answer:

he angular velocity w = 4.19 rad / s

Step-by-step explanation:

The girl is synchronized with the movement of the rope, therefore we can describe the movement of the girl with the angular velocity

w = θ/t

if we fear 40 jumps and each one is a revolution

θ = 40 2pi = 80π radiation

t = 1 min = 60 s

w = 80π / 60

w = 4.19 rad / s

this must be the same angular velocity of the rope
