Problem conducted an experiment on a particle's movement. The resulting data of a particle's movement was curve-fit generating the relation x = 5t3 + 2t2 - 42t + 20, where x is expressed in feet and t in seconds. Determine: (a) when the velocity is zero (b) the velocities and accelerations when x = 0.
