Two cars P and Q starts from a point at the same time in a straight line and their positions are represents by xp(t) = at + bt^2 and xQ (t) = ft − t^2. At what time do the cars have the same velocity? if she remains stationary on the moving escalator Preeti reached the metro station and found that the escalator was not working. She walked up the stationary escalator in time t1. On other days then the escalator takes her up in time t2. The time taken by her walk up on the moving escalator will be: August 27, 2020 Category: Chapter 3 - Motion in a Straight Line , NEET Last 32 Years Solved 1988 - 2019 Physics and Chemistry Video Solutions , Physics , Facebook Messenger WhatsApp Share this:TwitterFacebook Related Preeti reached the metro station and found that the escalator was not working. She walked up the stationary escalator in time t1. On other days, if she remains stationary on the moving escalator, then the escalator takes her up in time t2. The time taken by her walk up on the moving escalator will be:A person walks up a stationary escalation in t 1 second. If he remains stationary on the escalator, then it can take him up in t 2 second. If the length of the escalator is L, 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?A person walks up a stationary escalator in t1 . If he remains stationary on the escalator. Then it can take him up in t2. How much time would it take him to walk up her moving escalator ?
