The figure shows an overhead view of a 0.026 kg lemon half and two of the three horizontal forces that act on it as it is ona frictionless table. Force F has a magnitude of 3 N and is at 8, -31. Force F2 has a magnitude of 10 N and is at 02 33". In unit-vector notation, what is the third force if the lemon half (a) is stationary, (b) has the constant velocity V= (137-14) m/s, %3D %3D and (c) has the V = (12fi - 14) m/s?, where t is time?
