A particle at the origin starts motion from rest along the x axis with acceleration a = 6t2, where a is in m/s? andt is in seconds. The average velocity of the particle as it travels from x-8m to x = 128 m is:

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
