Fun Time, Inc., has just designed a new amusement-park ride based on the spinning disk concept. In order to operate the new ride, the velocity at different times is needed.
What is known:
The main disk rotates at Ω = 1 rad/s (θ = Ωt).
The rider disk rotates at ω = 2 rad/s (β = ωt).
Both angular velocities are constant.
What is the velocity of the rider, shown in the dynamic diagram at left, at 2.4 seconds?
Use the relative velocity equation for rotating coordinates,
vB = vA + Ω
× rB/A + vB/A
