Biomechanics Question. Please Help! Hey everyone, I need help with the following question: Vertical velocity of the hip = 2.1 m/sec Horizontal velocity of the hip = 1.7 m/sec Angular velocity of thigh = 4.6 rad/sec Thigh length = 0.36 m a) Calculate the absolute horizontal velocity of the knee when the thigh is perpendicular to the ground. Calculate the velocity of the knee with respect to the hip at any point (assume that the hip velocites are constants). c) Calculate the absolute horzontal velocity of the knee when the thigh is at an angle of -36 degrees (with respect to the horizontal) and travelling in a counterclockwise direction. Thanks in advance for your help!
