1. The problem statement, all variables and given/known data A 0.5kg block is being slid up a chalkboard with an applied force of 6.0N upward and 2.0N inward towards the board. If the coefficient of kinetic friction is 0.4: find the force of friction and the acceleration of the block. 2. Relevant equations coefficient of kinetic friction=force of friction/force normal force of gravity=mass*acceleration 3. The attempt at a solution for force of friction: 0.4=force of friction/0.5 =0.8 for acceleration: 8N=0.5/acceleration acceleration=16m/s/s Is the above method and answer correct? need help.
