1. The problem statement, all variables and given/known data Convert 83km/hr to m/s^2 2. Relevant equations Simple I know...but I still can't figure it out 3. The attempt at a solution 83km/hr(10^3m/km)(1hr/60min)(1min/60sec) The units cancel however leaving me with m/s not with m/s^2. The seconds^2 is what I cannot figure out. Thanks in advance!
