A particle moves in two dimension with acceleration of 5 m/s directed along the negative direction of the x axis. The particle starts from the origin with an initial velocity of (121 + 6) a. Find the maximum x coordinate the particle reaches. b. Find the cartesian equation of the trajectory of the particle. Hint: the trajectory is given by the equation f(x,y) = 0 and can be found by eliminating the time in the equations for the x and y positions.
