Running on a treadmill is slightly easier than running outside because there is no drag force to work against. Suppose a 60 kg runner completes a 5.0 km race in 15 minutes. Determine the drag force on the runner during the race. Suppose that the cross-section area of the runner is 0.72 m2. What is this force as a fraction of the runner's weight?

Experimental tests have shown that bone will rupture if it is subjected to a force density of 1.03 x 108 N/m2. Suppose a 70.0-kg person carelessly rollerskates into an overhead metal beam that hits his forehead andcompletely stops his forward motion. If the area of contact with the person’s forehead is 1.5 cm2, what is the greatest speed with which he can hit the wall without breaking any bone if his head is in contact with the beam for 10.0 ms?
Calculate the ratio of the drag force on a jet flying at 878 km/h at an altitude of 9.8 km to the drag force on a prop-driven transport flying at half that speed and altitude. The density of air is 0.39 kg/m3 at 9.8 km and 0.68 kg/m3 at 4.9 km. Assume that the airplanes have the same effective cross-sectional area and drag coefficient C.
The normal force of the ground on the foot can reach three times a runner’s body weight when the foot strikes the pavement. By what amount does the 52-cm-long femur of an 80 kg runner compress at this moment? The cross-section area of the bone of the femur can be taken as 5.2 x 10-4 m2.

a box slides down a ramp with an acceleration of 1.2m/s^2. if the coefficient of firction is 0.3 between the box and the ramp, what is the angle the ramo makes with the horizontal? You can leave your awnser as an equation/expression rather than finding the value.
Oceanographers use submerged sonar systems, towed by a cable from a ship, to map the ocean floor. In addition to their downward weight, there are buoyant forces and forces from the flowing water that allow them to travel in a horizontal path. One such submersible has a cross-section area of 1.3 m2, a drag coefficient of 1.2, and, when towed at 5.1 m/s, the tow cable makes an angle of 30° with the horizontal. What is the tension in the cable?
