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.(adsbygoogle = window.adsbygoogle || []).push({});

(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) ??
