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!
