Question
A particle starts from the origin at t = 0 s with a velocity of 10.0 ^j m/s and moves in the x-y plane with a constant acceleration of (8.0^i+2.0^j) m/s2.
(a) At what time is the x- coordinate of the particle 16 m? What is the y-coordinate of the particle at that time?
(b)What is the speed of the particle at the time ?
