Final answer:
Physics - A weight of 20 pounds stretches a spring. Find the spring constant and the force required to compress the spring.
Step-by-step explanation:
The subject of this question is Physics.
In this question, a weight of 20 pounds stretches a spring by 1/3 foot. The weight on the spring is then placed into a medium that offers resistance approximately 1/2 the velocity of the object. The problem likely involves the concept of force constant, which relates the force exerted by a spring to its displacement.
To find the spring constant, we can use Hooke's law: F = kx, where F is the force applied, k is the spring constant, and x is the displacement of the spring. We can then find the force required to compress the spring using the equation F = ma, where F is the force, m is the mass of the object, and a is the acceleration.
