4.08 Quiz: Acceleration
A ball accelerates uniformly at -2.00 m/s?
If the ball was initially moving at 0.20 m/s and the ball travels for 7.00 s, then what was its final velocity?

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].
