A small, battery-powered, electric motorboat that can travel at a speed of 1.95 m/s in still water is operating in a river with a flow speed of 1.35 m/s. For each of the following two cases, determine the requested information for a river that is 234 m wide. (a) Case 1: when the boat is pointed straight across the river, determine the speed vbl of the boat as viewed by someone on land, the distance d the boat is swept downstream before reaching the other side, and the time ti it takes the boat to make the crossing. Vbl = m/s d = m t1 = (b) Case 2: if the boat operator wants to land the boat straight across the river from the launch site, determine the speed vbi of the boat as viewed by someone on land, the angle ß upstream at which the boat should be pointed, and the time t2 it takes the boat to make the crossing. Vbl= m/s t2 =

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 0.435 m above his mouth. What angle (in degrees) above the horizontal must he spit? Assume vfy = 0.

A skydiver jumped out of a plane to shoot a skydiving scene for a certain spy movie. At what point in time should this spy-wannabe open his parachute when he is aware that the plane was at the altitude of 4435.43m and he needs to open it at a height of 206.83m?
A diver explores a shallow reef off the coast of Belize. She initially swims 90.0 m north, makes a turn to the east and continues for 200.0 m, then follows a big grouper for 80.0 m in the direction 30 north of east. In the meantime, a local current displaces her by 150.0 m south. Assuming the current is no longer present, in what direction and how far should she now swim to come back to the point where she started?
a firefighter located a distance of 24.5 m from a burning building directs a stream of water at an angle theta = 19.0 degrees above the horizontal at what height from the hose nozzle does the water strikes the building if the initial speed pf the stream is 34.0 m/s?
A fireman d = 32.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of θi = 31.0° above the horizontal as shown in the figure. If the speed of the stream as it leaves the hose is vi = 40.0 m/s, at what height will the stream of water strike the building?
You want to swim straight across a river that is 76m wide. You find that you can do this if you swim at an angle of θ= 28° from the upstream direction at a constant rate of 1.5 m/s relative to the water. At what rate does the river flow? The angle θ is measured from the river bank (directly upstream is θ=0 while directly across the river is θ= 90)
A small, experimental aluminum airplane leaves its classified location on a foggy and overcast day, and flies at 198 km/h (= 55.0 m/s), at a constant height h of 500 m, toward a point directly over a victim of a bizarre, classified experiment, floating in a remote mountain lake, where a rescue capsule is to land. (a) What should be the angle φ of the alien pilot’s line of sight to the victim when the capsule release is made? (b) As the capsule reaches the water, what is its velocity ⃗v?
A pilot wishes to make a flight of 300.0km [N30E] in 45min. On checking with the meteorogical office, she finds that there will be a wind of 80.0 km/h from the East for the entire flight. What heading and airspeed must she use for the flight?
A sailboat sails from Marblehead Harbor directly east for 45 nautical miles, then 60 degree south of east for 20 nautical miles, returns to an easterly heading for 30 nautical miles, and sails 30 degreeeast of north for 10 nautical miles, then west for 62 nautical miles. At that time the boat becomes becalmed and the auxiliary engine fails to start. The crew decides to notify the Coast Guard of their position. What is their position?
