1. The problem statement, all variables and given/known data fgrav = mg fgrav = (0.0821)(9.8) = 0.80458 N fnet = ma = (0.0821)(0.0096) = 0.0096 m/s^2 fnorm = fgrav 2. Relevant equations kinetic mew = force of friction / fnorm 3. The attempt at a solution Required: Ffr kinetic mew = force of friction / fnorm kinetic mew = force of friction / 0.80458 N I need to find the friction of the object when it is on the water. The object is made out of styrofoam. I'm completely stumped and I tried looking around internet using the google search engine to find the coefficient of friction of two surfaces.
