Question

I keep on getting 217.9 N but apparently that's wrong for this problem: A block is at rest on the incline shown in
the figure. The coefficients of static and kinetic friction are µs = 0.62 and µk = 0.53,
respectively. What is the frictional force acting on the
41 kg mass?

Answer 1

I'm getting this by smgcos(theta)

Answer 2

pic?

Answer 3

It looks like number 6 on this problem: http://mysite.cherokee.k12.ga.us/personal/kelly_burke/site/B%20Unit%203%20pdfs/1/HW%20Practice%20with%20Friction.pdf

Answer 4

only the mass is 41 kg

Answer 5

in that pic, you're applying two forces.
that pic is not related to the current question i feel

Answer 6

more over, that pic is not about inclined plane

Answer 7

the top force is not in my picture

Answer 8

it helps if u can draw the pic

Answer 9

oh! It's number 12

Answer 10

sorry, wrong problem

Answer 11

or 15 I guess

Answer 12

Theta = 29

Answer 13

Mass is 41 kg

Answer 14

ohk makes sense nw :)
let me see...

Answer 15

im also getting 217.88

Answer 16

dang it. I hate this stupid program my professor uses :/

Answer 17

but glad to know it's not me
