When they are far apart, the momentum of a proton is <3.4 × 10^(-21), 0, 0> kg·m/s as it approaches another proton that is initially at rest. The two protons repel each other electrically, without coming close enough to touch. When they are once again far apart, one of the protons now has momentum <2.7 × 10^(-21), 1.3 × 10^(-21), 0> kg·m/s.
At that instant, what is the momentum of the other proton? (Express your answer in vector form.)

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].
