Question: The position of a particle moving along an x axis is given by x = 14.0t2 - 3.00t3, where x is in meters and t is in seconds. Determine
(a) the position,
(b) the velocity, and
(c) the acceleration of the particle at t = 6.00 s.
(d) What is the maximum positive coordinate reached by the particle and
(e) at what time is it reached?
(f) What is the maximum positive velocity reached by the particle and
(g) at what time is it reached?
(h) What is the acceleration of the particle at the instant the particle is not moving (other than at t = 0)?
(i) Determine the average velocity of the particle between t = 0 and t = 6.00 s.
Two particles rest at a distance d apart on the edge of a table. One of the particles of mass m, falls off the edge and falls vertically. Using the other particle (still at rest) as the origin, (a) calculate the torque ? on m as a function of time..
