You want to move a heavy box with mass 30.0 across a carpeted floor. You pull hard on one of the edges of the box at an angle 30 above the horizontal with a force of magnitude 240 , causing the box to move horizontally. The force of friction between the moving box and the floor has magnitude 41.5 . What is the box's acceleration just after it begins to move?
Find both the x and y components of the acceleration of the box.
Enter the x and y components of the acceleration in meters per second squared, separated by commas.

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].
