A particle starts from origin
at t=0 with a velocity 5.0 m/s and moves
in x-y plane under action of a force which
produces a constant acceleration of
(3.0i+2.oſ) m/s. (a) What is the
y-coordinate of the particle at the instant
its x-coordinate is 84 m? (b) What is the
speed of the particle at this time?
