A moving 2.7 kg block collides with ahorizontal spring whose spring constant is 426N/m. The block compresses the spring a maximumdistance of 15.0 cm from its rest position. The coefficient 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 being dissipatedby the force of friction while the block is being brought to restby the spring?
C) What is the speed of the block when it hit sthe spring?
