The figure shows an overhead view of a 0.0220 kg lemon half and two of the three horizontal forces that act on it as it is on a frictionless table. Force F 1 has a magnitude of 5.00 N and is at 01 = 34.0. Force F 2 has a magnitude of 7.00 N and is at 02 = 29.0 In unit-vector notation, what is the third force if the lemon half (a) is stationary, (b) has the constant velocity U = (13.0i - 13.0j ) m/s, and (c) has the varying velocity U = (13.0ti - 12.0tj ) m/s, where t is time? X (a) Number -1.98 it 0.598 7 Units N (b) Number -1.98 i + 0.598 Units N (c) Number -1.69 i + 0.334 i Units N
