... Consider the propulsion of a fish through the water. A fish uses its fins to push water backwards. In turn, the water reacts by pushing the fish forwards, propelling the fish through the water. The size of the force on the water equals the size of the force on the fish; the direction of the force on ...

... • A supertanker of mass m = 1.50 × 108 kg is being towed by two tugboats, as in Figure 4.31a. The tensions in the towing cables apply the forces T1 and T2 at equal angles of 30.0° with respect to the tanker's axis. In addition, the tanker's engines produce a forward drive force D, whose magnitude is ...

Net force is equal to her weight minus her air drag, and being that air drag, increases with speed, net force and hence ...
