A block is initially at position x = 0 and in contact with an uncompressed spring of negligible mass. The block
is pushed back along a frictionless surface from position xr = 0 to x = -D, as shown above, compressing the
spring by an amount Ax = D. The block is then released. At x = 0 the block enters a rough part of the track
and eventually comes to rest at position x = 3D. The coefficient of kinetic friction between the block and the
rough track is u.
(a) On the axes below, sketch and label graphs of the following two quantities as a function of the position
of the block between x = -D and x = 3D. You do not need to calculate values for the vertical axis, but the
