1. ok don't know if this is the right section but here i go. The being asked is compare the work done by gravity to the change in potential energy? There is a system, but thas not important what is important is that the mass is falling at an acceleration of 2.789 m/s squared.
2. So i found the change in potential by doing mgh final - mga initial. i used the acceleration of 2.789 instead of 9.8 as g though. The when i attempted to find the work done by gravity i don't know if i should use 2.789 or 9.8.
3. Might sound like a jumple but i have no concrete answer to go upon so this is the best i could do. Basically i want to know which accelerations i should be using since its all jumbled in my head. I am also aware that W done by the conservative force (gravity in this case) is equal to the negative potential chnage. I just need help getting there
