1. The problem statement, all variables and given/known data A motorcycle traveling at 30 m/s comes to a stop over a distance of 150 m. What was the motorcycle's acceleration? 2. Relevant equations v^2=vinitial+2aΔx 3. The attempt at a solution I tried plugging in what I know. 0=900+2a*150 m Then I divided 150 m and 900 by 150: 0=6+2a This yields an answer of -4. It doesn't seem right, but I can't place why. I think I may have needed to divide the v^2 by 150, but that's 0/150, which wouldn't make sense. Thanks in advance for a reply!
