Question

17. [1pt Answer True, False, or Cannot tell to each of the five statements below E.g, if the answer to the first statemsent is true' and to the rest, cannot telf, enter TCCCC a. The graph shows the force required to stretch two springs as a function of their length. Spring 2 feels stiffer than spring1 b. A bobsled is pushed to compress a giant spring. The bobsled is let go onto frictionless horizontal ice. The graph represents the situation accurately Spring PE position c. A particle with energy E, moving to the right spoeds up as it moves from d to e d. A particle with energy E, could move from B to C. e. A spring (constant R) is stretched d: a second spring (constant k/2) is stretched 2d. There is more PE stored in the second spring. Answer:

Explanation / Answer

1. For same force distance x of spring 2 is less, therefore spring 2 is striffer. (TRUE)

2. TRUE. All the kinetic energy will be converted to potential energy of spring.

3.TRUE, As the particle moves from d to c its potential energy decreases but the kinetic energy increases therefore velocity increases.

4.False, to move from b to c particle needs energy greater than E2.

5.True, since PE = 1/2Kx2 . for 1st spring PE = 1/2Kd2 for 2nd spring PE = 1/2(k/2)(2d)2 = Kd2.
