# Forces

**1. The problem statement, all variables and given/known data**

Find the applied force for a object if the coefficient of kinetic friction equals 0.30 and the acceleration equals 5m/s^2. The applied force makes a 40 degree angle with the horizontal. The mass of the object is 10kg.

**2. Relevant equations**

Fnet=ma

**3. The attempt at a solution**

Ff=(0.3)(10)(9.8)=29.4

(coefficient)(normal force=mg)

Fnet =Facos40-29.4

Fnet=ma

ma=Facos40-29.4

Fa=103.6

I don’t know if I did this right. Can someone please explain to me how to do this correctly. Thanks!
