The Mass in the Figure Below Slides on a Frictionless $-\frac{k_{1}+k_{2}}{2}\left(x_{1}+x_{2}\right)$

question 10

Multiple Choice

The mass in the figure below slides on a frictionless surface. When the mass is pulled out, spring 1 is stretched a distance x1 from its equilibrium position and spring 2 is stretched a distance x2. The spring constants are k1 and k2 respectively. The force pulling back on the mass is:

• A)(-k2x1.)
• B)(-k2x2.)
• C)(-(k1x1 + k2x2).)
• D) \(-\frac{k_{1}+k_{2}}{2}\left(x_{1}+x_{2}\right)\) .
• E) \(-\frac{k_{1}+k_{2}}{k_{1} k_{2}}\left(x_{1}+x_{2}\right)\) .

Definitions:

Occipital Lobe

Positioned at the brain's posterior, this segment of the cerebral cortex is charged with the analysis of visual stimuli.

Frontal Lobe

is the part of the brain located at the front of each cerebral hemisphere, responsible for voluntary movement, expressive language, and managing higher level executive functions.

Cerebrospinal Fluid

A transparent, colorless fluid located in the brain and spinal cord, serving as a protective padding for the brain's cortex, offering fundamental mechanical and immunological defense.

Spinal Cord

The cylindrical bundle of nerve fibers and associated tissue that is enclosed in the spine and connects nearly all parts of the body to the brain.
