The only two forces acting on a body have magnitudes of 20 N and 35 N, and directions that differ by 80°. The resulting acceleration has a magnitude of 20 m/s2. What is the mass of the body?

Aballet student who learns with the of his instructor is demonstrating learning.

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].
