Question

If P = 100 N (Force) , M=45kg, and angle is 25degrees, what are the magnitudes for the following force?

b) The frictional force acting on the box

anonymous · Answer

Im not sure how to find the frictional force. I know its Ff = mew(f) Fn

zephyr141 · Answer

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

zephyr141 · Answer

ok quickly. i have a mid term in a few minutes. lol.

anonymous · Answer

so on the y component its Fn - mgcos( ) 
on the x component its Ff - Fapp

is this on a hill?

zephyr141 · Answer

or is the force at the 25 degree angle?
