The electric fan is mounted on a swivel support such that the fan rotates about the z axis at a constant rate of ω_z = 1 rad/s and the fan blade is spinning at a constant rate ω_s = 60 rad/s. If at the instant ϕ = 45°, ϕ̇ = 2 rad/s for the motion, determine the angular velocity and the angular acceleration of the blade.
