In a physics experiment on static friction, two objects made

of identical material are tied together with string. the fi rst

object has a mass of 5.0 kg and the second object has

a mass of 3.0 kg. students measure the maximum force

of static friction as 31.4 n to move both objects across a

horizontal surface. t/i

(b) what is the magnitude of the tension in the string if

they pull on the fi rst object?

(c) a student pushes the 3.0 kg object with a force of

15.0 [down]. what are the magnitudes of the maximum

force of static friction and the tension now?

(d) will your answers to (c) change if the student pushes

down on the 5.0 kg object instead? explain.

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].
