Forces and Newton's Laws of motion

[Qwap]

What is the magnitude of the force F (assumed horizontal) required to push the block up the plane at a constant speed? Take the coefficient of kinetic friction to be 0.25. Block is 75 lb

I used Ff= mewN and found Wparallel

Did Ʃ=ma
Fapp-Ff-Wparallel= ma

but i keep getting wrong answer

What is the angle of the incline?

Show your calculations for these terms

Did Ʃ=ma
Fapp-Ff-Wparallel= ma

but i keep getting wrong answer

You need first to calculate the parallel , and perpendicular to the incline, components of F app before solving by using Newton's laws in both dirctions.
