Scenario
Keshaun and Myra went to the amusement park last summer. They noticed that the roller coaster
was slower on the way up but went fast as they were on the way down. Keshaun's favorite part
was the first drop, but Myra liked it when they were going a little slower.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r Γ f) Β· 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, β5, 4] n, r = [β3, 5, 2] m, and n = [6, 5, β7].
