Problem: An 8.0-kg block is sliding down a wall with constant velocity. The coefficient of static friction between the block and the wall is = 0.70. The coefficient of kinetic friction between the block and the wall is = 0.40.
Part A: What is the magnitude of the force (in N) pressing the block against the wall?
I need help to find the magnitude of the force (in N) pressing the block against the wall and use g = 9.79 m/s2.
