A suspicious physics student watches a stunt performed at an ice show. In the stunt, a performer shoots an arrow into a bale of hay (Fig. P11.24). Another performer rides on the bale of hay like a cowboy. After the arrow enters the bale, the balearrow system slides roughly 5 m along the ice. Estimate the initial speed of the arrow. Is there a trick to this stunt? FIGURE P11.24

You are watching a National Geographic Special on television. One segment of the program is about archerfish which inhabit streams in southeast Asia. This fish actually spits drops of water at insects to knock them into the water so it can eat them. The commentator states that the archerfish keeps its mouth at the surface of the pond and squirts a jet of water from its mouth at a speed of 4 m/s. You watch an archerfish shoot a juicy mosquito off a leaf and into the stream. You estimate that the leaf was about 3/4 of a meter above the stream. You wonder at what minimum angle from the horizontal must the fish shoot a water droplet in order to hit the mosquito. Since you have time during the commercial break, you quickly calculate this angle using conservation of energy.
A forest fire is easiest to attack when it’s just getting started. In remote locations, this often means using airplanes to rapidly deliver large quantities of water and fire suppressant to the blaze. The “Superscooper” is an amphibious aircraft that can pick up a 6000 kg load of water by skimming over the surface of a river or lake and scooping water directly into its storage tanks. As it approaches the water’s surface at a speed of 35 m/s, an empty Superscooper has a mass of 13,000 kg.a. It takes the plane 12 s to pick up a full load of water. If we ignore the force on the plane due to the thrust of its propellers, what is its speed immediately after picking up the water?b. What is the impulse delivered to the plane by the water?c. What is the average force of the water on the plane?d. The plane then flies over the fire zone at 40 m/s. It releases water by opening doors in the belly of the plane, allowing the water to fall straight down with respect…
