Use the unit circle to see that and and you're given
my problem has been resolved this far but i cant transpose or what ever you call it
rearrange the formula
ive been getting help and have ended up with this
24.5 - x.cos(30). = u(42.44 + x.sin(30))
where u is cofficient of friction 1/7 or 0.143
also should the brackets be around the 30??
30 is the angle X is at
so 5g is resolved but cant work out X
49cos30= 42.44
49sin30= 24.5
but i cannot work it out. sure you all know what its like after a day of exams.
and a break down of how to work it would be great
