The average speed is 10 m/s.
Explanation:
The motion of the object is divided into two parts.
In the first part, the object covers a distance of
In a time interval of
In the second part, the object is a t rest, so it covers a distance of
In a time interval of
The average speed for the trip is given by the ratio between the total distance and the total time taken, therefore:

Answer:
The tangential velocity for the cars are approximately 2.3 m/s
Explanation:
The given parameters are;
The radius of the Texas Star Ferris wheel, r = 65.8 mete secondsrs
The time it takes the Ferris wheel to go round once = 180 seconds
The angular velocity, ω = Change in angle rotated/(Time duration of the change)
ω = Δθ/Δt = 2·π/180
The tangential velocity for the cars, = ω·r = 2 × 3.14/180 × 65.8 ≈ 2.3 m/s
The tangential velocity for the cars, ≈ 2.3 m/s.
