A spring and block are in the arrangement of Fig. 7-9. When the block is pulled out to x = +4.0 cm, we must apply a force of magnitUde 360 N to hold it there. We pull the block to x = 11 cm and then release PROS LEMS 161 it. How much work does the spring do on the block as the block moves from Xi = +5.0 cm to (a)x = +3.0 cm, (b)x = -3.0 cm,(c)x = -5.0cm,and(d)x = -9.0cm?
