The velocity is zero at point no 3 in ankle joint. It is because the angular position is zero.
At point no 4, flexion velocity is maximal for the Knee and Hip Joints.
At point no 2, extension velocity is maximal for the Knee and Hip Joints.
At point no 2, dorsiflexion velocity is maximal for the Ankle joint.
At point no 4, plantarflexion velocity is maximal for the Ankle joint.
