two people kick a ball. one of them kicks it with a force of 215.0 newtons. the other one with 189.0 newtons. their approach creates a 210.0 degree angle at the point of impact and causes the ball to go in a different direction. what is the resultant of the vector from this impact?
i got 107.5365772 newtons. is this correct?

magnitude^2=215^2+189^2-2*215*210*cos(30degrees)=61^2N
81,946 - 90,300*cos(30degrees) = 61^2 N
3,743.9 = 61^2 N
3,743.9 = 3,721 N
1.006 = N
was i suppose to solve it out like that?
3,743.9 = 61^2 N
3,743.9 = 3,721 N
1.006 = N

Hardly.
if
magnitude^2=61^2
then magnitude is 61N
if
magnitude^2=61^2
then magnitude is 61N
