need someone to explain please
could someone please explain this equation for me
E_H = E_{H- \Delta h} + \frac{1} {2} J \omega^2 + \frac{1} {2}m v^2
this is the equation just incase the one above didn't come out right
EH= EH- Delta h + 1/2 j omega^2 + 1/2 mv^2
somewhat
the 30 degree angle goes on top from the right end to the wall.
How do i figure that out with the equation f=ma when i don't have the acceleration.
Please help I'm totally lost an i don't understand how to do these problems.
Could u please explain these problems out so i can better understand them and solve too.I am failing physics right now that's how clueless i am about this subject.
