A production crew is filming a nature explorer in the Rocky Mountains. The explorer needs to swim across a river to hiscampsite. By watching debris flowing down the river, it can be estimated that the stream is flowing at 1.51 miles per hour. In stillwater, the explorer can swim at 1.63 miles per hour. At what angle with respect to the shoreline should the crew advise him toswim to travel directly across the stream to his campfire?angle:The temperature of the water is close to freezing. Typically, a human can swim in such water for about 5 min before hypothermiasets in. Calculate the time the explorer spends in the water if the river is 92.1 ft wide.time:minBased on the calculations, should the production crew allow the explorer to swim across the river to his campsite?Yes. The explorer will get cold, but he should be able to make it across the river.No. The explorer will not make it across the river in time, and so the crew will cancel the swim.

Given Velocity of the river vr = 1.5 mph Velocity of the swimmer vs = 1.63 mph

A landscape architect is planning an artificial waterfall in a city park. Water flowing at 0.750 m/s leaves the end of a horizontal channel at the top of a vertical wall h = 2.35 m high and falls into a pool (Fig. P3.54). (a) How far from the wall will the water land? Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, one-twelfth actual size. How fast should the water flow in the channel in the model? Figure P3.54

A whale dives from the surface of the ocean at an angle of 30° below the horizontal and followed a linear path of 50 m long. How far below the water surface is the whale at this point? 50 m (50 m)/sin 30° (50 m) sin 30° (50 m) cos 30°
Brandon is on one side of a river that is 60 m60 m wide and wants to reach a point 300 m300 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 2 m/s2 m/s and run at 4 m/s.
An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.395 m above his mouth. A) What angle (in degrees) above the horizontal must he spit? (In degrees)
A pirate ship is 506 m away from a fort that is being defended by artillery that is sea level. The defensive cannon is capable of firing a cannon ball at 95 m/s. At what angle(s) above horizontal can the cannon fire the cannon ball so that it will hit the pirate ship?
A fire hose held near the ground shoots water at a speed of 5.9 m/sm/s. At what angle(s) should the nozzle point in order that the water land 2.5 mm away? Express your answer(s) in degrees to two significant figures. If there is more than one answer, separate them by a comma.

An explorer is caught in a whiteout (in which the snowfall is so thick that the ground cannot be distinguished from the sky) while returning to base camp. He was supposed to travel due north for 5.6 km, but when the snow clears, he discovers that he actually traveled 7.8 km at 50° north of due east. (a) How far and (b) in what direction must he now travel to reach base camp?
One strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching this first snowball, you throw a second snowball at a low angle and time it to arrive at the same time as the first. Assume both snowballs are thrown with the same initial speed 20.5 m/s. The first snowball is thrown at an angle of 68◦ above the horizontal. At what angle should you throw the second snowball to make it hit the same point as the first? The acceleration of gravity is 9.8 m/s 2 . Answer in units of ◦ .

Assume both snowballs are thrown with the same initial speed 32.1 m/s. The first snowball is thrown at an angle of 57◦ above the horizontal. At what angle should you throw the second snowball to make it hit the same point as the first? Note the starting and ending heights are the same. The acceleration of gravity is 9.8 m/s 2
