A camera operator is filming a nature explorer in the Rocky Mountains. The explorer needs to swim across a river to his campsite. By watching debris flowing down the river, the operator estimates that the stream is flowing at 0.625 m/s0.625 m/s . In still water, the explorer can swim at 0.735 m/s0.735 m/s . At what angle, less than 90°, with respect to the shoreline should the operator advise him to swim so that he travels directly across the stream to his campfire The water is near freezing in temperature. Typically a human can only swim in such water for about 300 s300 s (or 5 min5 min ) before hypothermia sets in. Calculate the time the explorer spends in the water if the river is 27.9 m27.9 m wide.

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 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°

The Gateway Arch, in St. Louis Missouri, is the tallest monument in the United States, at approximately 192 meters tall. A camera is 50 meters from the base of the monument and is moving along the horizontal ground away from the monument while keeping the top of the monument in view. What is the camera’s horizontal velocity when its angle of elevation (to the top of the monument) is decreasing at 0.2 radians per second?
Goku, flying at an altitude of 210 m above the surface of the ocean, sees Vegeta below the surface who is at an actual depth of 360 m. How far is Goku from the surface of the ocean as seen by Vegeta? 157.5 m 270 m 280 m 480 m
When a man stands near the edge of an empty drainage ditch ofdepth 2.80 m, he can barely see the boundary between the oppositewall and bottom of the ditch as in Figure P22.47a. The distancefrom his eyes to the ground is 1.85 m. (a) What is the horizontaldistance d from the man to the edge of the drainage ditch?(b) After the drainage ditch is filled with water as in FigureP22.47b, what is the maximum distance x the man can standfrom the edge and still see the same boundary?
Snow is falling vertically at a constant speed of 7.8m/s. a) At what angle from the vertical and b) with what speed do the snowflakes appear to be falling as viewed by the driver of a car traveling on a straight road with a speed of 55km/h?
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. P3.70). (a) How far from the wall will the water land? Will the space behind the waterfall be wideenough 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?
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 ◦ .
A submarine dives from the water surface at an angle of 30° below the horizontal, following a straight path 50 m long. How far is the submarine then below the water surface? (a) 50 m (b) (50 m)/sin 30° (c) (50 m) sin 30° (d) (50 m) cos 30° (e) none of those answers.
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?
