An object slides on a level surface in the positive x direction. It slows and comes to a stop with a constant acceleration of -2.45 m/s/s. What is the coefficient of kinetic friction between the object and the floor?
a = F/m
The Attempt at a Solution
I have been sitting at my desk for about 15 minutes and am still scratching my head. I also don't even know what a "coefficient of friction" is, my teacher just told us that it is mu. What does it mean/represent?
However, I tried using a = F/m but don't know where to go from here...is that the right start? Thanks in advance
