A block of mass m = 2 kg is pushed against a spring of spring constant k = 30 N/m until the spring is compressed by x = 0.1 m. The block is released and travels across a rough table with a coefficient of kinetic friction of ?k = 0.05.
(a) What is the maximum speed of the block?
(b) How far does the block travel before stopping?
(c) How much farther or shorter would a 1 kg block travel? Explain.
