A particle starts from the origin at t=0 s with velocity of `10.0hat(j)m//s` and moves in the x-y plane with a constant acceleration of `(8.0hat(i) + 2.0hat(j))ms^(-2)`. A) At what time is the x-coordinate of the particle 16m? What is the y-coordinates of the particle at that time? b)What is the speed of the particle at the time?
