Vector V1 is 8.94 units long and points along the -x axis. Vector V2 is 4.13 units long and points at +35.0° to the +x axis.
(a) What are the x and y components of each vector?
so i got V1x=-8.94 and V1y=0 which is right
but i don't know how to get the V2x and V2y
i got V2x=4.99 or 5.00 and V2y=-2.76 but i got it wrong.
I solved for V by using V= V1 + V2 so i got V=-8.94 + 4.13 = -4.81. i got V2x by using Vx=Vcos(angle) so Vx=-4.81cos(35) = -3.94. Then i did -3.94=-8.94 + V2x and solved for V2x which i got 4.999 or 5.00. I got V2y by using Vy=Vsin(angle) so Vy=-4.81sin(35) = -2.76. Then i used Vy=V1y + V2y which is -2.76 = 0 + V2y and solved for V2y and got -2.76.
Am i doing this right? if I'm not how do i solve for them?
