A 5 kg block rests on a 30degree incline
the coefficient of static friction is between the block and incline is 0.2
how large a horizontal force must push on the block if the block is to be on the verge of sliding a)up the incline and b) down the incline
So far I have ma=Fapp-(m)mg-mgsin30
where (m) is miu or friction co-efficient
ive been working on this for a long time but not sure how to get the answers
any help will be much appreciated!
