The figure shows an overhead view of a 0.0200 kg lemon half and two of the three horizontal forces that act on it as it is on a frictionless table. Force
vec(F)_(1)has a magnitude of 3.00 N and is at
\theta _(1)=29.0\deg . Force
vec(F)_(2)has a magnitude of 11.0 N and is at
\theta _(2)=34.0\deg . In unit-vector notation, what is the third force if the lemon half (a) is stationary, (b) has the constant velocity
vec(v)=(11.0hat(i)-12.0widehat(j))(m)/(s), and (c) has the varying velocity
vec(v)=(14.0that(i)-11.0that(j))(m)/(s), where
