Question
Transcribed Image Text:The right leg of an athlete on a rowing machine can be modeled as a linkage as shown, where A represent the ankle (which is
stationary), K the knee, and H the hip. At the instant when 0 = 75°, the shank AK has an angular velocity of 1 rad/s and an angular
acceleration of 1.45 rad/s2, both counter-clockwise. Determine the velocity and acceleration of the hip Hat this instant in time.
