The position of a particle moving along an x axis is given, Ask an Expert

Academics

The position of a particle moving along an x axis is given by x = 22t2 - 3.0t3, where x is in meters and t is in seconds.

(a) Determine the position, velocity, and acceleration of the particle at t = 3.0 s. x = m v = m/s a = m/s2

(b) What is the maximum positive coordinate reached by the particle? m At what time is it reached? s

(d) What is the acceleration of the particle at the instant the particle is not moving (other than at t = 0)? m/s2

(e) Determine the average velocity of the particle between t = 0 and t = 3 s. m/s
