OC userin Physics·20 May 20185.67 - CP BIO Forces During Chin-ups. When you do a chin-up, you raise your chin just over a bar (the chinning bar), sup- porting yourself with only your arms. Typically, the body below the arms is raised by about 30 cm in a time of 1.0 S, starting from rest. Assume that the entire body of a 680-N person doing chin- ups is raised by 30 cm, and that half the 1.0 s is spent accelerating upward and the other half accelerating downward, uniformly in both cases. Draw a free-body diagram of the person's body, and use it to find the force his arms must exert on him during the accelerating part of the chin-up.
OC userin Physics·19 May 201811.34 - In the Challenger Deep of the Marianas Trench, the depth of seawater is 10.9 km and the pressure is 1.16 X 108 Pa (about 1.15 X 10° atm). (a) If a cubic meter of water is taken from the surface to this depth, what is the change in its volume? (Normal atmospheric pressure is about 1.0 X 10Pa. Assume that k for seawater is the same as the freshwater value given in Table 11.2.) (b) What is the density of seawater at this depth? (At the surface, seawater has a density of 1.03 X 10° kg/m”.)

OC userin Physics·20 May 20181.9. A certain fuel-efficient hybrid car gets gasoline mileage of 55.0 mpg (miles per gallon). (a) If you are driving this car in Europe and want to compare its mileage with that of other European cars, express this mileage in km/L (L = liter). Use the conversion factors in Appendix E. (b) If this car's gas tank holds 45 L, how many tanks of gas will you use to drive 1500 km?
