A particle is moving in a straight line and its distance x from a fixed point on the line at any time t seconds is given by, x = t4/12 – 2t3/3 + 3t2/2 + t + 15. What is the minimum velocity?

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.
