Resolving Vector Components with Trigonometry

Resolving Vector Components with Trigonometry Part A Find the components of the vector /vecA with length a = 1.00 and angle /alpha =15.0 /rm/circ with respect to the x axis as shown. Enter the x component followed by the y component, separated by a comma. /vec A = Part B Find the components of the vector /vec B with length b = 1.00 and angle /beta =20.0 /rm/circ with respect to the x axis as shown. Enter the x component followed by the y component, separated by a comma. /vec B = Part C Find the components of the vector /vec C with length c = 1.00 and angle /phi 30.0 /rm/circ as shown. Enter the x component followed by the y component, separated by a comma. /vec c =

Explanation / Answer

Part A x component of Vec A = 1*cos(15) = 0.966 y component of Vec A = 1*sin15 = 0.259 Part B x component of Vec B = 1*cos(20) = 0.939 y component of Vec B = 1*sin20 = 0.342 Part C y component of Vec C = 1*cos(30) = 0.866 x component of Vec C = 1*sin30 = 0.5
