Problem
The vertical displacement (in metres) of a thrown object is given by the quadratic polynomial g(x)=3x2−5x−2, where x is the time in seconds measured from the instant of projection.
(i) Find the times when the object is at ground level.
(ii) Comment briefly on the physical meaning of each value obtained.
