Problem 17E

A spring stores potential energy U0 when it is compressed a distance x0 from its uncompressed length. (a) In terms of U0, how much energy does the spring store when it is compressed (i) twice as much and (ii) half as much? (b) In terms of x0, how much must the spring be compressed from its uncompressed length to store (i) twice as much energy and (ii) half as much energy?

Step-by-Step Solution:
Step 1 of 3

Solution 17E When the spring gets compressed by a distance of x , the potential energy it stores is U 0 0 , which is equal to, U = 1 K x --------------------(1) 0 2 0 This is the potential energy of a spring compressed by x . 0 a) i) when the spring gets compressed twice as much, U = 1 K x = 1K (2x ) = 1 K × 4 x 2 2 2 0 2 0 = 4U 0 The potential energy would be 4 times as before. ii) When the spring gets compressed to half as much, 1 2 1 2 1 2 U = 2 K x = 2K (0.5x 0 = 2K × 0.25 × x 0 1 = U4. 0 The potential energy stored will be U . 4 0 b) i) to get a potential energy of 2U , the compressing must...
