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)

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
