The figure shows an overhead view of a 0.0250 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 8.00 N and is at 01 = 28.0. Force F 2 has a magnitude of 4.00 N and is at 02 = 26.0. In unit-vector notation, what is the third force if the lemon half (a) is stationary, (b) has the constant velocity U = (12.01 - 12.0j ) m/s, and (c) has the varying velocity 7 = (14.0ti - 14.0tj ) m/s, where t is time? (a) Number 5.31 it -0.161 i Units N (b) Number 5.31 it -0.161 Units N (c) Number i + HI i Units N
