using your graph paper, a protractor, and a centimeter scale, draw arrows to represent the forces F1 and F2 describe above. Choose a scale and draw each force vector so that its length is proportional to the magnitude of the force. The direction of each arrow must be the same direction as the force it represents. Using the heat to tail method, draw and arrow that represents the resultant of the two vectors. (Don't forget to record the scale you choose) take a photo and paste. From the length of the resultant vector R, determine its magnitude according to your scale. Using the protractor, determine the resultant vector's direction (angle). Record your results in the table below.

COMPONENT METHOD

Using your calculator, determine the x and y components of F1 and F2. Remember that Fx=Fcos0 and Fy=Fsin0. Find the x and y components of the resultant from the sumof x and y components. Calculate the magnitude of the resultant force from the square root of (R2+R 2). Calculate the direction of the resultant force from 0R=tan-1(Ry/Rx). Does this result agree with the graphical method?
