Four forces are applied on an object as shown in the figure. The magnitudes of the forces are F1= 5 N, F2=9 N, F1= 3 N, and F=10 N. The angle 0 = 60°. During the displacement: a) What is the net work done on the object? b) Does the kinetic energy of the object increase or decrease? (2.5+2.5) Four forces are applied on an object as shown in the figure. The magnitudes of the forces are F1= 5 N, F2=9 N, F1= 3 N, and F=10 N. The angle 0 = 60°.
