## Homework Statement

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.

## Homework Equations

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

=0.8

for acceleration:

8N=0.5/acceleration

acceleration=16m/s/s

Is the above method and answer correct? need help.
