A 5 kg block, an inclined plane with an angle of 53, and uk = 0.5 are present. Attached to the bottom of the inclined lane, the massless spring with a force constant of k= 300 N/m is initially not stretched. The block has an initial speed of vo as it slides down the incline, and there is an initial L = 40 cm gap between it and the spring. The spring can be compressed by the block up to a maximum of d = 40 cm. a) How much work does the spring do up until it reaches its maximum compression? b) How much work does friction accomplish up until maximal compression? c) How much is vo? d) What is the lowest value of the , following the maximal compression, at which the block cannot rebound up the incline?
