The distance x of a particle moving along a straight line from a fixed point on the line at time t after start is given by t = ax2 + bx + c (a, b, c are positive constants). If v be the velocity of the particle at the instant, then which one is correct?

MCQs on calculus applications like increasing and decreasing functions, tangents and normals, straight line motion, motion under gravity, calculus applications like maxima and minima, acceleration and velocity.
