1. The problem statement, all variables and given/known data On a level road a motorcycle slows down with an acceleration of -3.40 m/s^2. Calculate the value of its acceleration when the road goes up hill 15 degrees. 2. Relevant equations Fnet = MA 3. The attempt at a solution I tried setting up a system of equations and made friction equal. Level road: friction force = ma Inclined road: friction + wsin(theta) = ma2 Ma= ma2-wsin(theta) Ma = ma2 - mgsin(theta) A = a2 - gsin(theta) A2 = A + gsin(theta) A2 = -3.40 + (-9.8)(sin15) But the answer isn't -5.94, so I don't know what I'm doing wrong. Thanks.
