A block weighing 50.0 newtons is on a ramp inclined at 45.0° to the horizontal. A 20.0-newton force of friction, F1, acts on the block as it is pulled up the ramp at constant velocity v with a force F2 that is parallel to the ramp, as shown in the diagram below. What is the magnitude of force F2?

A. 49.5 N
B. 55.4 N
C. 367 N
D. 486 N

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].
