1. The problem statement, all variables and given/known data a.) a box slides down a 30 degree ramp with an acceleration of 1.20 m/s^2. Determine the kinetic friction between the box and the ramp. 2. Relevant equations 3. The attempt at a solution the equation is uk=Fk/Fn but they did not provide me with atleast one force or one mass to figure out the Force normal or even force gravity so i am completely lost. please help.
