Hello students, so in this question for a, for a, velocity of, of b of b is expressed as, expressed as, so vb equals to omega a, b multiplied by 7, which is equal to 3 multiplied by 7, which will be equals to 21 inch per second.
00:25
Now vc equals to vb plus omega multiplied by vc divided by v.
00:33
Consider this as first.
00:34
So from here we'll get vc equals to minus vc multiplied by 4 divided by 5 i minus vc vc multiplied by 3 divided by 5 i consider this as second.
00:49
So we will get r cv equals to minus 5.

I cap minus 12 j cap and v v v equals to minus 21 i cap i cap now putting this in equation first we will get vc vector equals to minus 21 i cap minus 5 omega j cap plus 12 omega i cap now consider this as third so equating now equate equate equate first and second and first and third third so we will get minus 0 .8 vc i cap minus 0 .6 vc j cap equals to minus 21 plus 12 omega i cap minus 5 omega j cap so which will be equals to minus 21 plus 12 omega j cap so which will be equals to minus 21 plus 12 omega equals to 0 .8 vc consider this as 8 and 0.

Minus 0 .6 vc equals to minus 5 omega now consider this as v so on solving on solving on solving equation a and b we will get vc equals to 9 .375 inch per second and omega equals to 0 .12 vc so which so from here will get omec equals to 9 .375 inch per second and omega equals to omega equals to 1 .25 radian per second...
