Q1. A person's heart and head are 1.2m and 1.7m above the feet, respectively. Find out the potential energy associated with 0.50 kg of blood in the heart relative to a) feet b) head.
Q2. If the mass of both weights is 150 gm, the first mass is located 30 north of east, the second mass is located 30 south of east, and the transducer sensitivity is 0.5 volts/Newton, how large a voltage do you expect to measure? Suppose the transducer has been properly zeroed so that V = 0 while F3=0.
