GIVING A MEDAL! Two forces with magnitudes of 25 and 30 pounds act on an object at angles of 10° and 100° respectively. Find the direction and magnitude of the resultant force. Round to two decimal places in all intermediate steps and in your final answer.

OpenStudy (anonymous):

Is this vectors

OpenStudy (mayaal):

yes:)

OpenStudy (anonymous):

precalc?

OpenStudy (mayaal):

yep

OpenStudy (anonymous):

do u have like questions on a piece of paper or anything u can upload, i'd like a visual

OpenStudy (mayaal):

unfortunately,they didn't give me one:(

OpenStudy (anonymous):

so the magnitude is 25 and 30

OpenStudy (mayaal):

yes.........

OpenStudy (anonymous):

you can find the component form with this magnitude(cos(direction), sin(direction)

OpenStudy (mayaal):

ok,so would i have to find 2 different component forms b/c v have 2 magnitudes?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

but the direction is 90 is 100-10

OpenStudy (anonymous):

so i would write this

OpenStudy (anonymous):

25( cos90 , sin 90)

OpenStudy (anonymous):

distribute

OpenStudy (mayaal):

ok,so would it be: 25cos90 , 25sin 90 =0,25

OpenStudy (mayaal):

????

OpenStudy (mayaal):

can anyone plz help me?@ganeshie8 ?
