Hello Yvette K.,

Wyzant Ask-an-Expert is not a spreadsheet for solving your homework set. That's 7 problems at once on the same skill set, using physics equations for forces, energies, masses, momenta, and so on. That's spamming. Please limit yourself to a single problem, get the technique from the answer, and apply it yourself from there on. If you are totally at sea on applying equations to problems, please find some one-on-one tutoring; Wyzant makes that possible, or perhaps your peers, family, friends, etc..
