You encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground.
How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway?
Express your answer using one significant figure.
Mike and Josh, two bicycles from towns d = 24 kilometers apart, set off in the same direction at the same time. Both Josh and Mike cycled at v, = 25 km/h. Instantly after they begin, a fly flies from Josh at the University of Michigan to Mike, and then immediately returns to Josh. Until the riders meet, the fly continues to fly back and forth between the cyclists. Air speed of fly is UF = 30 km/h, and wind velocity u = 10 km/h constantly blows toward Mike. s is the entire length of time that the fly has been airborne in meters. D (up-uy) 21Km GFLYI+Vmtavelled, both GFLYI+Vmtavelled
Your friend is standing at the balcony of a building which is H meter high from the ground while
you are standing at the parking lot situated at the ground level. Now you realize that you got the
wrong keys of your car so you decided to throw the wrong keys to your friend and ask her to
drop the original keys. She dropped the keys and at the same instant you threw the keys
straight up with a speed of u. Determine the height at which both sets of keys cross each other.
Take H=160 m,u=40 m/s and g=10 m/s^2
