zale101 for part a ΔPE=PEf−PEi or the correct way to write this is ΔEtotal=PEgravity+PEspring
OpenStudy (zale101):
I'm confused because it asks for ΔPE but there's two different kinds of PE, the PE gravity and the PE spring...
OpenStudy (mathmate):
The only potential energy that has changed "at the end of the slope" is gravitational potential energy, because at the end of the slope, the block has not reached the spring yet.
OpenStudy (zale101):
That makes sense. Thanks!
