## Homework Statement

You gradually apply a force to a 10. kg wood block on a wood table. What will the applied force on the block be once it is moving? The coefficients of static and kinetic friction are 0.5 and 0.3, respectively. The acceleration due to gravity is 9.8 m/s2.

## Homework Equations

N = w= mg

Fk = μkN

Fsmax = μsN

## The Attempt at a Solution

N = w = mg = (10 kg)(9.8 m/s2) = 98 N

Fsmax = μsN = (0.5)(98 N) = 49 N (wrong!)

Is this correct?

N = w = mg = (10 kg)(9.8 m/s2) = 98 N

Fk = μkN = (0.3)(98 N) = 30 N
