The position of a particle moving along an x axis is given by x = 12t^2 . . . The position of a particle moving along an x axis is given by x = 12t 2 - 2t 3, 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 = 3 0 s (d) What is the maximum positive coordinate reached by the particle and (e) at what time is it reached? (f) What is the maxi- mum positive velocity reached by the particle
The angular acceleration of the disk is defined by alpha = (3t2 + 12 . . . The angular acceleration of the disk is defined by α = (3 t 2 + 12) r a d s 2, where t is in seconds If the disk is originally rotating at ω o = 12 rad s, determine the magnitude of the velocity and the n and t components of acceleration of point A on the disk when t = 2 s
