The roller coasters potential energy is greater at point 1 because, it's the beginning and the energy hasn't yet been used. When it reaches point 4 the energy is low because it was just moving.
I hope this helps I might be wrong and there was no picture to go along with the problem :)
The first answer is 112 because you multiply 9 by 7 to get 63 and then you multiply 16 by 7 to get 112. and the second one is 27 because 16 times 3 equals 48 so then you multiply 9 by 3 to get 27.:)
The answer is you could by 6 games. mostly because you would have 10 dollors left . so now you can add me as a friend my name is angel1600 yessss.
