In the swing carousel amusement park ride, riders sit in chairs that are attached by a chain to a large rotating drum as shown in (Figure 1). As the carousel turns, the riders move in a large circle with the chains tilted out from the vertical. In one such carousel, the riders move in a 16.5−m-radius circle and take 8.3 s to complete one revolution. Figure 1 of 1 What is the angle of the chains, as measured from the vertical? Express your answer in degrees. θ = ∘
