A block of mass 1.3 kg is attached to a horizontal spring that has a force constant 800 N/m as shown in the figure below. The spring is compressed 2.0 cm and is then released from rest.  A constant friction force of 3.8 N retards the block's motion from the moment it is released. a) How much is the spring compressed when the speed of the block is a maximum? b) What is the maximum speed?
