Divya received the following problem. A particle moves in a straight line with velocity v of t is equal to the square root of three t minus one meters per second, where t is time in seconds. At t equals two, the particle's distance from the starting point was eight meters in the positive direction. What is the particle's position at t equals seven seconds? Which expression should Divya use to solve the problem? So pause this video and have a go at it. All right, now let's do this together.
