A small 0.45-kg box is launched from rest by a horizontal spring as shown in the figure below. The block slides on a track down a hill and comes to rest at a distance d from the base of
the hill. The coefficient of kinetic friction between the box and the track is 0.40 along the entire track. The spring has a spring constant of 32.5 N/m and is compressed 30.0 cm with the
box attached. The block remains on the track at all times.
