A 72.5 kg man stands on a horizontal surface. HINT (a) What is the volume of the man's body (in m³) if his average density is 989 kg/m³? m3 (b) What average pressure (in Pa) from his weight is exerted on the horizontal surface if his two feet have a combined area of 4.65 x 10-2 m?? Pa

a) Determine the total force and the absolute pressure on the bottom of a swimming pool 25.0 meters by 9.5 meters, whose uniform water depth is 2.0 meters. b) what will be the pressure against the side of the pool near the bottom?

A horizontal segment of pipe tapers from a cross-sectional area of 44.6 cm2 to 0.500 cm2. The pressure at the larger end of the pipe is 1.30 × 105 Pa, and the speed is 0.0400 m/s. What is the pressure at the narrow end of the segment? ___Pa

A person who weighs 671 N is riding a 85-N mountain bike. Suppose the entire weight of the rider plus bike is supported equally by the two tires.
