A stream flows at a rate of 3.9 km/hr. A boat has a speed of 7.6 km/hr. While in the stream the boat travels upstream a distance of 2 km as measured along the shore, then travels back downstream to its starting point. Neglect the time to turn around. a. Find the time it takes the boat to go upstream b. Find the time it takes the boat to do downstream c. What would it have taken to make the entire round trip in still water?

A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 146 feet per second from an initial height of 89 feet off the ground, then the height of the projectile, h, in feet, t seconds after it's shot is given by the equation: h=−16t2+146t+89h=-16t2+146t+89 Find the two points in time when the object is 126 feet above the ground (to one decimal places). Answer: The object is 126 feet off the ground at the following times: (Enter your two answers separated by a comma. Round to ONE decimal places.)

You watch a player on the OSU football team and observe that he runs for 2.62 km. Is the displacement of the player the same as the distance traveled? If not, why not?
A person walks up a stalled 15-m-long escalator in 90 s. When standing on the same escalator, now moving, the person is carried up in 60 s. How much time would it take that person to walk up the moving escalator? Does the answer depend on the length of the escalator?
If the entire length of the picket fence is 25 cm, how much time (in seconds) would it take to fall through the photogate, if its leading edge enters at 0.0 m/s
A helicopter leaves its base and travels 20.0 km north. After a brief stop, it flies 35.7 km south, pauses briefly and then flies 17.0 km north. Finally, it flies 6.0 km south and lands. At the end of the trip, what is the displacement of the helicopter from its base?
An unidentified flying object (UFO) is observed to travel a total distance of 19000 m, starting and ending at rest, over a duration of 4.23 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2.
