An athlete with a mass of 70 kg is performing a barbell back squat exercise with a load of 150 kg. From the starting position (position A), the athlete stands still prior to lowering their COM in the negative vertical direction at a rate of -1.45 m/s2 (position B). Once they reach the bottom position, they hold the squat for 3 seconds (e.g. 0 m/s2 – position C). After the 3 second period, the athlete raises their COM in the positive vertical direction at a rate of 2.55 m/s2 (position D) back to the starting position. Solve for the net force at each position to allow the athlete to achieve the respective accelerations during the barbell back squat lift.

A person is performing walking gait trials across a laboratory. At heel strike the hip flexion angular velocity is 0.70 rad/s, knee flexion angular velocity is 4.15 rad/s, and ankle plantar flexion angular velocity is -0.70 rad/s. Additionally, moment of inertia of the hip is 0.70 kgm2, moment of inertia of the knee is 0.90 kgm2, and moment of inertia of the ankle is 1.00 kgm2. What is the sagittal plane angular momentum of the hip, knee, and ankle joints at heel strike?
Once this person transitions through the stance phase to toe off (e.g. propulsion) the hip flexion angular velocity increases to 3.15 rad/s, knee flexion angular velocity is 4.95 rad/s, and ankle plantar flexion angular velocity is –8.10 rad/s. If we assume gait velocity is constant during the stance phase, what is the moment of inertia of the hip (mass of femur = 8.50 kg), knee (mass of shank = 2.60 kg), and ankle (mass of foot = 0.82 kg) at toe off? Furthermore, what is the radius of gyration of the hip, knee, and ankle at toe off?
