There are two forces on the 2.46 kg box in the overhead view of the figure but only one is shown. For F1 = 19.0 N, a = 10.0 m/s2, and 0 = 33.0, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction. (State the direction as a negative angle measured from the +x direction.) (a) Number i Units (b) Number Units (c) Number Units
