7.39

7.39 • A block with mass 0.50 kg is forced against a horizontal
spring of negligible mass, compressing the spring a distance of 0.20 m
(Fig. P7.39). When released, the block moves on a horizontal table-
top for 1.00 m before coming to rest. The force constant k is 100 N/m.
What is the coefficient of kinetic friction uk between the block and the
tabletop?
