Explanation / Answer

A = 77 grams @109 degree ; B = (25.1) xunitvector + (-72.8) yunit vector C = (-260) xunit vector + (-180) yunit vector assume grams as the unit what is Ax, Ay ?
Ax=77cos109=-25.06
Ay=77sin109=72.80
what is the magnitude of B
B=25.1*25.1+72.8*72.8=74.36 what is the direction of B in radians counter clockwise fromthe positive x axis?
tan=72.8/25.1=>=70.97
it is making an angle of 70.97with -ve X axis
so t is making an angle of (180-70.97=109.02)with +ve X axis what is the x-component of the Equilibrant of A+B+C ?
once we have all the vectors with their componennts add all the Xcomponents what is the equation for vector Ay and the equationfor the magnitude of A (using A's x and y components)
Ay=77sin109=72.80
A=25.06*25.06+72.8*72.8=76.99 assume grams as the unit what is Ax, Ay ?
Ax=77cos109=-25.06
Ay=77sin109=72.80
what is the magnitude of B
B=25.1*25.1+72.8*72.8=74.36 what is the direction of B in radians counter clockwise fromthe positive x axis?
tan=72.8/25.1=>=70.97
it is making an angle of 70.97with -ve X axis
so t is making an angle of (180-70.97=109.02)with +ve X axis what is the x-component of the Equilibrant of A+B+C ?
once we have all the vectors with their componennts add all the Xcomponents what is the equation for vector Ay and the equationfor the magnitude of A (using A's x and y components)
Ay=77sin109=72.80
A=25.06*25.06+72.8*72.8=76.99
