The position x of a particle with respect to time t along x−axis is given by x = 9t^2 − t^3 where x is in metres and t in seconds. What will be the position of this particle when it achieves maximum speed along the + x direction? A car moves from X to Y with a uniform speed vu and returns to Y with a uniform speed vd. The average speed for this round trip is 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
