The right leg of an athlete on a rowing machine can be modeled as a linkage as shown, where A represents the ankle (which is stationary), K the knee, and H the hip. At the instant when θ = 75°, the shank AK has an angular velocity of 1 rad/s and an angular acceleration of 1.5 rad/s², both counterclockwise. Determine the velocity and acceleration of the hip H at this instant in time.
