A small 0.55-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 0.34 along the entire track. The spring has a spring constant of 36.5 N/m and is compressed 30.0 cm with the box attached. The block remains on the track at all times. 300 cm- 50.0 cm 40 e (a) What would you include in the system? Explain your choice.
