- If you swim with the current in a river, your speed is increased by the speed of the water; if you swim against the current, your speed is decreased by the water’s speed. The current in a river flows at 0.52 m/s. In still water you can swim at 1.78 m/s. If you swim downstream a certain distance, then back again upstream, how much longer, in percent, does it take compared to the same trip in still water?If you double the initial speed of a projectile, what happens to that projectiles range? Assume that the projectile lands at the same height from which it was launchedTwo very hungry (and competitive) pre-med students suddenly see a parked ice cream truck that is that is down to its last ice cream cone. The truck is a distance of D meters away from the nearest student, who runs toward the truck at 2.5 m/s, and the second student (who was a track star in high school) runs toward it faster at 5.7 m/s but the second student is 10.0 meters farther away (to where he has to run D+10.0 m). What is the maximum possible value of D for the two students to reach the ice cream truck at the same time?
- 2 airplanes leave an airport at the same time. the velocity of the 1st airplane is 680 M/H at a heading of the 51.6 Degrees the velocity of the 2nd is 640M/h at a heading of 176ﾟ how far apart are they after 2 . 3 hour answering units of MIf you fire a projectile at various speeds, does this change the time that the projectile is in the air? Explain why or why not?
