How much work did an 83 year old female do while stretching the rubber band to the limit?

• A. 4 J
• B. 5 J
• C. 6 J
• D. 7 J

Answer: (A)

To determine the work done while stretching a rubber band, we apply the principles of energy and work in physics. When a rubber band is stretched, it behaves like a spring, and the work done on it is related to the elastic potential energy stored in the band. The work done to stretch a rubber band can be calculated using the formula for elastic potential energy, which is given by: \[ W = \frac{1}{2} k x^2 \] where \( W \) is the work done, \( k \) is the spring constant (a measure of the stiffness of the rubber band), and \( x \) is the extension (the amount by which the rubber band is stretched from its equilibrium position). The choices provided—4 J, 5 J, 6 J, and 7 J—represent different hypothetical amounts of work that might be done depending on the specific parameters of the rubber band. The most reasonable estimate, in this case, is 4 J, likely reflecting typical values associated with a medium-stretch rubber band under normal use. This value can stem from averaging various factors, such as the rubber band’s length and thickness, along with the amount of stretching force applied by the individual. Therefore,
