N (b) If the area of each of the 68.0-kg acrobat's shoes is 480 cm2, what average pressure (not including atmospheric pressure) does the column of acrobats exert on the floor? Pa (c) Will the pressure be the same if a different acrobat is on the bottom?

In a tug-of-war game on one campus, 15 students pull on a rope at both ends in an effort to displace the central knot to one side or the other. Two students pull with force 196 N each to the light, four students pull with force 98 N each to the left, five students pull with force 62 N each to the left, three students pull with force 150 N each to the right, and one student pulls with force 250 N to the left.

Using the same force table that you used, a student was given two forces and asked to find a single force that would produce equilibrium with the two forces. The two forces were given by providing one of the components and the angle the force made with the positive x- axis. The two forces were as follows: Force 1: ?? = −2.70 ?; ? = 220.0 degreees Force 2: ?? = 3.20 ?; ? = 60.0 degrees (a) For each force, calculate the magnitude of the force and the mass required to produce it. (b) Calculate the mass and its angle of application to produce equilibrium with these two forces. Please specify your angle as counterclockwise positive with respect to the positive x-axis.
