In a measurement of a man’s density he is found to have a mass of 75.0 kg in air and an apparent mass of 2.25 kg when completely submerged in water with his lungs empty. he has a lung capacity of two and half liters. (a) what mass of water does he displace? (b) determine his volume. (c) calculate his density. (d) if his lungs are half filled with air, will he float or sink? (show calculation. yes/no without calculations give you zero points.) (e) if his lungs are completely filled with air, will he float or sink?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
