Hooke's Law States That the Force F Required to Compress

question 16

Multiple Choice

Hooke's Law states that the force F required to compress or stretch a spring (within its elastic limits) is proportional to the distance d that the spring is compressed or stretched from its original length. That is, where k is a measure of the stiffness of the spring and is called the spring constant. The table shows the elongation d in centimeters of a spring when a force of F newtons is applied. Use the model to estimate the elongation of the spring when a force of 55 newtons is applied. Round your answer to two decimal places.

• A) 8.08 cm
• B) 6.38 cm
• C) 4.68 cm
• D) 2.98 cm
• E) 9.78 cm
