If a ball with some kinetic energy collides with a spring, the ball doesn't lose its kinetic energy in an instant, right? it loses kinetic energy as the spring gains potential elastic energy. Right?
So now I'm wondering. If I have a spring on the ground, and If I let the block falls from some meteres to collide with the spring on the ground. How can I calculate the maximum compression of the spring ?
I was thinking like this: The block has an Initial potential energy, that it's going to convert to kinetic energy, and at the time that the block collides with the spring the whole kinetic energy would transfer to the spring, so I could calculate all about the spring doing this:
say X is the initial potential energy of the BLOCK. Total Energy= Kinetic energy of the spring + Elastic Potential energy of the spring (=) X= Kinetic energy of the spring + Elastic Potential energy of the spring
But now I'm wondering if it wouldn't be more accurate to say that X= Kinetic energy of the spring + Elastic Potential energy of the spring - Kinetic energy of the ball !!
What do you think?
