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)

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

i had this question and the answer was 3.15 miles.
