Physics 50 Proficiency Test 1(sample) (Time: 15 minutes) 25 points By Todd Sauke Name ________________________ Section # ________ The three forces described below act on an object at the origin of a coordinate system. The given angles are measured counterclockwise around from the + x axis unless other- wise specified. The "newton", letter symbol N, is a unit of force in the metric system. F 1 = 64.0 N at –17 º F 2 = 18.0 N at 0.46 rad F 3 = 47.0 N at 43 º clockwise from the negative y axis. Convert the angle given in rad (radians) to degrees. F 2 = ______________ º Sketch the three forces as approximately scaled arrows on a coordinate system below. Use enough accuracy to show approximate length and which quadrant each vector is in. Make a vector addition table as in class for summing the components of these vectors

F 1x = F 1y = F 2x = F 2y = F 3x = F 3y = ______________________ _______________________ R x = R y = (over) Copy the previous result to this page for convenience: R x = R y = Sketch another coordinate axis system below, lay off appropriate scales on its axes, and construct the resultant vector R . On your sketch label at least the components of R , the angle from the + x axis, θ R , and an additional convenient angle to help get θ R . Calculate the magnitude of R & the standard angle θ R in degrees & radians. | R | = ______________________ N θ R = ______________________ º θ R = ______________________ rad...
