Im not sure how to find the frictional force. I know its Ff = mew(f) Fn
you have to draw a free body diagram and go from there. you need to seperate the force into x and y components using the angle of 25 degrees. use Newton's 2nd law and find the total force in the x and in the y directions.
okay i have a big big big question
ok quickly. i have a mid term in a few minutes. lol.
so on the y component its Fn - mgcos( ) on the x component its Ff - Fapp
