In the answer, it gives a formula f-ff=m(0) and afterwards simplies into 120 - ff = 0 and further into ff=120N. My question is how do you not have to divide by 0 to finish the equation if that makes sense. To simply further why are we able to ignore the m(0) portion?
That's what I thought too! But the answer choices it gave were 8 m/s, 4 m/s, 2 m/s, and 6 m/s so I'm confused. I went with 8 and it was wrong.
