A particle of mass 2 kg rest on a rough plane incline at an angle to the horizontal. The particle is subjected to a force of FN  of the plane along greatest slope when  f=5 the particle is about to slide down the plane when f=19 the particle is about to slide up  the plane calculate the value of thetha and the coefficient of friction between the particle and the plane.​

900 degrees

step-by-step explanation:

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0

i have no clue what you just said. write a question in english?

is there supposed to be a picture here?
