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.
coefficient of kinetic friction=force of friction/force normal
force of gravity=mass*acceleration
The Attempt at a Solution
for force of friction:
0.4=force of friction/0.5
Is the above method and answer correct? need help.
