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 +xaxis unless other-wise specified. The "newton", letter symbol N, is a unit of force in the metric system. F1= 64.0 N at –17 º F2= 18.0 N at 0.46 rad F3= 47.0 N at 43 º clockwise from the negative yaxis. Convert the angle given in rad (radians) to degrees. F2= ______________ º Sketch the three forces as approximatelyscaled 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
