(1/2) k x^2 Joules
k = 267 N/m
x = 0.07 m
A moving 1.6 kg block collides with a horizontal spring whose spring constant is 267 N/m (see figure). The block compresses the spring a maximum distance of 7.0 cm from its rest position. The coefficient of kinetic friction between the block and the horizontal surface is 0.19. What is the work done by the spring in bringing the block to rest?
