A straight section of a small river has a steady current of 2.0 km/h. Two docks on the same side of the river are separated by 2.4 km. One afternoon Bob and Alice decide to have a race, there and back, between the two docks. Bob walks along the shore at a constant speed of 4.0 km/h for the entire round trip. Alice's mode of transport is a canoe. Her speed with respect to the water is a constant 4.0 km/h for the entire round trip. (a) How long does it take Bob to complete the race? Calculate a numerical value for the time. (b) How long does it take Alice to complete the race? Calculate a numerical value for the time.

Before jumping from the bridge, Martin throws his water bottle to a friend standing on the bank of the lake. The bridge is 7.0 m high. The friend is standing on the bank 15.0 m from the base of the bridge with their hand 1.0m above the ground. What speed must Martin throw the bottle horizontally for it to reach his friend's hand?
A river 109.5 m wide flows toward the south at 35.0 m/min. A girl on the west bank wishes to reach the east bank in the least possible time. She can swim 109.5 m in still water in 1.10min. How long does it take her to cross the river? Also how far downstream does she travel? What is her velocity relative to land?find the magnitude and direction south of east? Also what is the total distance she traveled? And last in what direction must she swim if she wishes to travel straight across the river?
A spacecraft has an initial speed of 3037 m/s at an angle of 27 degrees above the positive x axis. Two engines fire for 5.4 seconds, and produce an acceleration of 9.9 m/s/s at an angle of 18.5 degrees above the positive x axis. What is the final speed of the spacecraft? What angle is it at above the positive x-axis?
A Lockheed Martin F-35 Lightning II jet takes off from an aircraft carrier with a runway length of 107 m and a takeoff speed 77 m/s at the end of the runway. Jets are catapulted into airspace from the deck of an aircraft carrier with two sources of propulsion: the jet propulsion and the catapult. At the point of leaving the deck of the aircraft carrier, the F-35's acceleration decreases to a constant acceleration of 4.8 m/s2 at 23° with respect to the horizontal. (Assume that the F-35's initial direction along the deck of the aircraft carrier is the +x-direction and that the +y-direction is up.) What is its velocity and speed at this time? (Enter your answers in m/s.) v(5.4 s)= (?î +?ĵ) v(5.4 s)= ? m/s How far (in m) has it traveled horizontally?
A river flows due east. A boat travels with constant speed due north across the river from point A to point B. The speed of the boat relative to the water is 5 m/s. The river is 21m wide and it takes 7s to travel from A to B. What is the speed of the current in the river?
After a constant acceleration of 3.52 m/s/s at 9.6 degrees above the +x-axis is applied by the motors of a boat for 7.05 seconds, the boat is moving at 96.8 m/s at 34 degrees above the +x-axis. What was the displacement of the boat during this time? What is the angle from the positive x-axis?
For this problem, you can think of the jet stream as a river of air. Across the United States, the jet stream usually moves from west to east. We will assume that the jet stream is moving in its usual direction at 9.00 x 101 km/hr. On a particular day, you need to pilot a plane from one city to another that is 4.50 x 102 km directly to the south. The top speed of the aircraft in still air is 285 km/hr. (a) Make a sketch to represent what is happening in this problem. Label all quantities that you know. (b) Using cardinal directions (north, east, south, west) to give a heading, which direction should you aim the plane to reach the city directly to the south at top speed? (c) How fast (in km/hr) would you be moving relative to the ground? (c) How much time (in hr) will it take you to reach your destination?

Alice, Bruce, Chad, and Dave are enjoying a trip to the amusement park. Alice rides the Ferris Wheel (47.75 meters in diameter), but Bruce decides simply to watch. Chad and Dave are riding the monorail that passes along a straight track just below the Ferris Wheel's bottom. The monorail moves at a constant speed of 9 m/s. The first time that Alice passes Bruce (who is standing right next to Alice but on the ground), Alice and Bruce look at their watches, and Chad (who happens to be passing under Alice's seat on the Ferris Wheel at that instant) looks at the clock on her seat's fancy electronic display. This is event A. When Alice passes Bruce the next time (call this event B), Alice and Bruce again look at their watches, and Dave, who happens to be passing under Alice's position at just that instant, looks at his display (which we assume is synchronized with Chad's display). Everyone determines the time interval that they measure between these momentous events (Chad and Dave by…
