Vbr and Vr ka vector sum should give Vb but it doesnt (direction wise)

..?

Wait im thinking

Vb+Vr=Vbr na vector wise its correct na
CorrodedCoffin
CorrodedCoffinOP5d ago
Vbr = Vb-Vr vel of b wrt r

Or ek tarike se aisa soch skta hai ki Vb ka ek component Vr ko cancle krna chaye waha se bhi sin theta 1/2 ayega Yeah vector wise

logically it makes sense vector se nahi ban rhi

Ban to rha hai? Vector triangle dekh waha pr jo banra

Are wait we messed up something Vb should be Vbr and Vbr should be Vb Ulta likh dia mene cause vese dekho to Vb right me ni ja skta wrna wo drift hi kar jayega river ke sath

mitr logically your soln makes complete sense meine bhi whi kara tha pehle but vector triangle kyu galat aa rha 😭

Wahi me soch ra☠️ @hardcoreisdead the velocity of boat which is given.. Ye wrt river to nahi
CorrodedCoffin
CorrodedCoffinOP5d ago
matlab?
Real potato
Real potato5d ago
8kmph Relative velocity to nahi? Sense tbhi banra hai
