Find the scalar x- and y-components of the following displacements in the XY-plane: (a) 300 cm at 127° and (b) 500 cm at 220°
(a) x=300sin1270=239.59cm.x=300\sin{127^0}=239.59 cm.x=300sin1270=239.59cm.
y=300cos1270=−180.54cm.y=300\cos{127^0}=-180.54 cm.y=300cos1270=−180.54cm.
(b) x=500sin2200=−321.39cm.x=500\sin{220^0}=-321.39cm.x=500sin2200=−321.39cm.
y=500cos2200=−383.02cm.y=500\cos{220^0}=-383.02 cm.y=500cos2200=−383.02cm.
