There are two forces on the 1.1 kg box in the overhead view of Fig. 5-37 but only one is shown. The figure also shows the acceleration of the box. IMAGE : http://www.webassign.net/hrw/05_37.gif (a) Find the second force in unit-vector notation. N i + N j (b) Find the second force as a magnitude and direction. N, ° (counterclockwise from the +x-axis is positive) I'm not exactly sure where to start. Using F=ma then F= (1.1)(12)=13.2 so is the net Force 13.2 and for N in part be would the answer be either 20tan(30) or 20/tan(30) ??
