| Jan 10, 2017 at 3:08 | comment | added | Alex Vlasov | Thank you @JohnForkosh that equivalence made it click, I was drawing my test triangles wrong. How should I go about closing my question? | |
| Jan 10, 2017 at 2:27 | comment | added | UKH | Build some right angled triangles. See what happens if you change one of the acute angles, keeping the altitude a constant. | |
| Jan 10, 2017 at 2:17 | comment | added | Bill N | Also, the kinetic energies at beginning and end are NOT the same unless you let the pig actually hit the ground, but then you have the ground doing work on the pig, too. | |
| Jan 10, 2017 at 2:15 | comment | added | Bill N | What direction is the gravitational force? How far do the pigs move parallel to the gravitational force? The cosine factor simply picks out the parallel distance. | |
