1. A prosthetic lower leg has a mass of 1.81 kg and a COM of 21 cm from the knee joint. The radius of gyration (about the center of mass) is 14.1 cm. (a) Calculate mass moment of inertia of the lower leg about the knee joint, Ik . (b) If the distance between the knee and hip joints is 42 cm, calculate Ih for this prosthesis about the hip joint as the amputee swings through with a locked knee. (c) If the radius of gyration (about the center of mass) increases to 17 cm, how does this affect Ik calculated in part (a)

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
