Quiz 4a – Hooke’s Law

1. A physics student stretches an elastic band 20cm and applies a force of 11N in doing so. What is the spring constant of the elastic band?

2. A student puts a 0.150 kg arrow in a bow and pulls back distorting the bow by 0.45 m. If the spring constant of the bow is 25 N/m what is the initial acceleration of the arrow when it is released?

3. What is the missing word?Hooke’s Law: The size of an elastic force is proportional to the _______________________of the object.
