A moving 2.7 kg block collides with ahorizontal spring whose spring constant is 426N/m (see figure). The block compresses the springa maximum distance of 15.0 cm from its rest position. Th ecoefficient of kinetic friction between the block and the horizontal surface is 0.14.
A) What is the work done by the spring in bringing the block torest?
B) How much mechanical energy is beingdissipated by the force of friction while the block is being brought to rest by the spring?
C) What is the speed of the block when it hitsthe spring?
