A particle P starts to move from a point O and travels in a
straight line. At time ts after P starts to
move its velocity is v ms-1, where v - 0.12t - 0.0006t2.
(i) Verify that P comes to instantaneous rest when t = 200,
and find the acceleration with which it
starts to return towards O.
(ii) Find the maximum speed of P for 0 <= t <= 200.
(iii) Find the displacement of P from O when t = 200.
(iv) Find the value of t when P reaches O again.
