PE = 1/2kx^2
Work external = Delta KE + Delta PE
W = F* d
The Attempt at a Solution
In the pictures.Comments:
On Problem 3 ai, I am not sure whether I have identified the correct horizontal forces. The hint gave two, but I believe there could also be a force that the wall exerts on the spring.
I am also not sure which way the force points when a spring is stretched and extended. I believe it is in the direction of the equilibrium unextended position. Please let me know if my answers/reasoning is correct. Thank you.
