A particle starts from the origin at t = 0 with an initial
velocity of 5.0 m/s along the positive x axis. If the acceleration
is (–3.0i + 4.5j) m/s^2, determine the velocity and position of the
particle at the moment it reaches its maximum x coordinate.
Can someone explain why
when the particle reaches it maximum x coordinate?
