6. The velocity, v m/s of a particle, travelling in a straight line, at time t s after leaving a fixed point O, is given by v = 3 + 2t - t 2, where t ≥0.
Estimate the distance of the particle from O when the velocity of the particle becomes zero.

quadratic (:

then this question is incorrect. are you sure you typed it correctly?

anonymous · Answer

hmm  but i copied and paste from my worksheet.

anonymous · Answer

you can estimate the time when the velocity is 0, not the distance, unless you have the formula for distance.
