Chapter 6, Problem 74GP

At a playground, a 22-kg child sits on a spinning merry-go-round as shown from above in Figure 6-71. The merry-go-round completes one revolution every 6.2 s, and the child sits at a radius of r = 1.4 m. (a) What is the force of static friction acting on the child? (b) What is the minimum coefficient of static friction between the child and the merry-go-round to keep the child from slipping?

Your blood pressure (usually given in units of "mm of Hg") is a result of the heart muscle pushing on your blood. The left side of the heart creates a pressure of 115 mm Hg by exerting a force directly on the blood over an effective area of 14.5 cm2. What force does it exert to accomplish this? (Give your answer as the number of Newtons and note that you will need to do some unit conversions.)

What is the absolute (total) pressure experienced by a diver at a depth of 17 meters below the surface of a lake? Assume that atmospheric pressure at the surface of the lake is 101,000 Pascals, g= 9.8 m/s2, and the density of the water in the lake is 997 kg/m3. Give your answer as the number of Pascals.
