Noor runs by Sura sitting on the floor by the library at a constant velocity of 3.5 m/s [S]. Sura notices that Noor grabbed her charger and starts from rest 2.5 s after Noor passes her. Sura accelerates continuously at 1.75 m/s² [S] until she catches Noor.(a)Determine the time it takes for Sura to catch Noor (as measured from the time the charger was grabbed)(b)Determine the time it takes for them to have the same velocity (as measured from when Sura moves)
