A person walks up a stationary escalation in t 1 second. If he remains stationary on the escalator ,
then a. Determine the speed of man with respect to the escalator. b. Determine the speed of the escalator. c. How much time would it take him to walk up the moving escalator? ,
then it can take him up in t 2 second. If the length of the escalator is L ,
Suppose you are riding a bike with a speed of 10ms −1 due east relative to a person A who is walking on the ground towards east. If your friend B walking on the ground due west measures your speed as 15ms −1 , find the relative velocity between two reference frames A and B.
