Two identical 0.25kg blocks (labeled 1 and 2) are initially at rest on a nearly frictionless surface, connected by an unstretched spring, as shown in the upper diagram, where x2=0.059m. Then a constant force of 17N to the right is applied to block 2, and at a later time the blocks are in the new positions shown in the lower diagram, where x1=0.01m and x3=0.108m. At this final time, the system is moving to the right and also vibrating, and the spring is stretched.
I included a picture of the given image.
Check all the forms of energy that change in the point particle system during this process:
Select all that are True.
Spring potential energy.
Vibrational kinetic energy.
Rotational kinetic energy.
Translational kinetic energy.
None necessary for this problem.[/B]
The Attempt at a Solution
I know there is a change in translational KE because it start from rest and doesn't end at rest.
I know there is a change in Spring PE because it initially started at rest, and ended in movement.
I know there is a change in Vibrational KE because it initially started at rest meaning very little vibration is
occurring and it ends in movement so that means their is an increase in Vibrational KE while PE is decreasing.
I believe there is a change in thermal energy cause it corresponds to Vibrational KE
I don't believe there is Rotational KE cause nothing is rotating/spinning.
