. A particle has an initial position vector r=0 and an initial velocity v0=3i +2j(where distance is measured in meters and velocity in meters per second).The particle moves with a constant acceleration a=i -4j(measured in m/s2).At what time does the particle reach a maximum y coordinate? What is the position vector of the particle at that time?
