(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1.)I can't get it why a friend of mine from this forum is getting 56.01N and me 56.70N

2.) I got this solution 50Ncos30-(0.02(20(9.8)-50sin30))/20, what did you get??

3.) (0.4(20x9.8))/cos30+(0.4(sin30)) what did you get?

2. Relevant equations

1)F= (0.1(50x9.8))/(cos25 - (0.1sin25))

2)50Ncos30-(0.02(20(9.8)-50sin30))/20

3) (0.4(20x9.8))/cos30+(0.4(sin30)) what did you get?

3. The attempt at a solution

1)F= (0.1(50x9.8))/(cos25 - (0.1sin25)) =56.70N

and my friend got 56.01N???

2) 50Ncos30-(0.02(20(9.8)-50sin30))/20=1.99m/s^2

3) (0.4(20x9.8))/cos30+(0.4(sin30))= 73.5N

all I'm asking is your answers on this following formula..
