Exercise 1: A horizontal spring has a constant k = 360 N/m. (a) How much work is required to compress it from its uncompressed length (x = 0) to x = 11cm? (b) If a block with mass m3D1.85 kg 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 a constant drag force FD = 7N is acting to slow it down, such as friction or perhaps your finger.
