A ride at an amusement park attaches people to a bungee cord, pulls them
straight down to the ground, and then releases them into the air. When they
are pulled to the ground, the bungee cord (which has a stiffness constant of
35 N/m) is stretched 100 m beyond its unloaded length. What restraining
force is required to hold a man with a mass of 100 kg to the ground just
before he is released? (Recall that g = 9.8 m/s2)
Force of bungee
100 m
Weight + Restraining Force
A. 2670 N
B. 2430 N
C. 2520 N
D. 2830 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].
