A block rests on an inclined as shown in figure, angle of the slope is θ. The Force F is applied so that the block just starts (barely) moving upward. Answer the following Question. A1 and A2 as well as F1 and F2 are the component of Force A and Force F.  Q PIC.png If, the Applied Force is 244.3 N, the mass of the block is 5 kg, the coefficient of static friction of the surface is 0.8, what is the slope?
