Owh, haha something could be wrong with my equ. However, this is my trial: 1) V(f)²= V(o)² + 2ad 3²= 0² + 2 (a)(10) 9= 20a 0.45 =a So, a= 0.45 m/s/s 2) μ = Ffriction/ Fnormal OR μ*Fnormal= Ffriction Fnet in x-axis: Ffriction - mg sin 25= ma (Ffriction - mg sin 25) ÷ m = a...

Homework Statement A box was dragged downward from the state of rest through an inclination 10.0 m at an angle of 25 degree. The speed when the box arrived at the base is 3 m/s. a) what is the coefficient force between the box and the surface? b) how many work is done to move the box downward...
