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
(Figure 1). When released, the block moves on a horizontal tabletop for 1.00 m
before coming to rest. The spring constant k
is 100 N/m
What is the coefficient of kinetic friction μk
between the block and the tabletop?
