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

The table (below) shows the force needed to push a 10-kg box up a ramp as the angles increase. From the trend in the table, what is the applied force needed if the angle of the ramp increases to 50 degrees?

Applied Force (N) ; Ramp Angle (Degrees)

19N ; 10 degrees

30N ; 20 degrees

40N ; 30 degrees

49N ; 40 degrees

2. Relevant equations

applied force = mg sin(degree of angle)

3. The attempt at a solution

I honestly don't know about this, and I'm not really looking for the answer to the problem, just the "how-to". I tried, with the equation above, to see if it worked for the 19N ; 10 degrees (in the table). My work looked like:

applied force = (10kg)(9.81)sin(10) = 17.0348....

This obviously isn't the 19N that I was supposed to get. I can't find any decent explanations for this problem, and would appreciate any help.
