A spring and block are in the arrangement of the figure. When the block is pulled out to x = +5.0 cm, we must apply a force of magnitude 360 N to hold it there. We pull the block to x = 12.0 cm and then release it.

A spring and block are in the arrangement of the figure. When the block is pulled out to x = +5.0 cm, we must apply a force of magnitude 36O N to hold it there. We pull the block to x = 12.0 cm and then release it. How much work does the spring do on the block when the block moves from x; = +5.0 cm to (a) x = +4.0 cm, (b) x = -4.0 cm, (c) x= -5.0 cm, and (d) x = -10.0 cm?

The figure shows three forces applied to a trunk that moves leftward by 2.58 m over a frictionless floor. The force magnitudes are F1 = 4.61 N, F2 = 9.46 N, and F3 = 3.04 N, and the indicated angle is 0 = 60°. (a) During the displacement, what is the net work done on the trunk by the three applied forces, the gravitational force, and the normal force? (b) Is there a net transfer of energy to or from the trunk? (c) Does the kinetic energy of the trunk increase or decrease? (a) Number i -0.36 Units J (b) from (c) decrease
