A person is attempting to pull a block of ice with mass m = 80 kg on a horizontal surface with coefficient of static friction µs = 0.5. The person applies force F, at angle 0 = 40° as shown in Figure 1. Calculate the minimum value of F, required to move the block. In other words, calculate the minimum force that the person must apply to overcome friction.

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?
