Give a specific example of a system with the energy transformation W→K . In this question, W is the work done on the system by the environment, and K and U are the kinetic and potential energies of the system, respectively. Any form of energy not mentioned in the transformation is assumed to remain constant. As part of your response, identify the objects that are in the system.

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].
