Problem
A 0.80kg block is launched up a smooth track with an initial speed of 4.0m/s at the bottom. The top of the track is 0.50m higher than the bottom and is connected to a horizontal spring of force constant 180N/m that is initially uncompressed. After reaching the top, the block compresses the spring and momentarily comes to rest. What is the maximum compression of the spring?
(a) 0.27m
(b) 0.17m
(c) 0.11m
(d) 0.22m
