Question 2 A certain spring has a resting length of 0.08 m (8 cm) when it is not stretched. The spring is stretched to a length of 0.10 m (10 cm), 0.02 m beyond its natural length. Holding it in this stretched position requires a force of 20 N. Hooke's Law says that the force required to maintain the spring in a stretched position is the linear function F (x) = kr. In this case, we have 20 = k - 0.02. Find the spring constant, k, for this spring. Note: please count your zeros carefully before entering your answer. Question 3 Consider the same spring as problem #2. Find the work that was required to extend the spring 0.02 m beyond its natural length. 2 Newton-meters 0.02 Newton-meters 0.2 Newton-meters 20 Newton-meters

Transcribed Image Text:Question 2
A certain spring has a resting length of 0.08 m (8 cm) when it is not stretched. The spring is stretched to a length of 0.10 m (10 cm), 0.02 m beyond its natural length. Holding it in this stretched
position requires a force of 20 N.
Hooke's Law says that the force required to maintain the spring in a stretched position is the linear function F (x) = kx.
In this case, we have 20 = k - 0.02.
Find the spring constant, k, for this spring.
