(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A block of mass 9 kg rests on a plane inclined

at an angle of 30◦

. The static coeﬃcient of

friction between the block and the plane is

0.7.

What is the frictional force on the block?

1. 9.36841 N

2. 76.3834 N

3. 53.4684 N

4. 44.1 N

5. 30.87

It is not # 3. I know that for sure.

2. Relevant equations

F=ma

F_{f}=μ*F_{n}

3. The attempt at a solution

I have no idea
