A horizontal spring has spring constant k = 360 N/m. (a) How

A horizontal spring has spring constant k = 360 N/m. (a) How much work is required to compress it from its uncompressed length (x = 0) to x = 11.0 cm? (b) If a 1.85-kg block is placed against the spring and the spring is released, what will be the speed of the block when it separates from the spring at x = 0? Ignore friction. (c) Repeat part (b) but assume that the block is moving on a table and that some kind of constant drag force FD 7.0 N is acting to slow it down, such as friction (or perhaps your finger). FD FN mg F = kx
