A Boat Streams In A River With Velocity 2I+5J Wrt Ground. The River Water Flows With A Velocity -3I-4J Wrt To The Ground. What Is The Relative Velocity Of Boat Wrt River Water?
Boat Streams In A River With Velocity 2I+5J Wrt Ground
Vb - Vg = 2i + 5j
The River Water Flows With A Velocity -3I-4J Wrt To The Ground
Vr - Vg = - 3i - 4j
The Relative Velocity Of Boat Wrt River Water
Vb - Vr
= (Vb - Vg) - (Vr - Vg)
= (2i + 5j) - (- 3i - 4j)
= 2i + 5j + 3i + 4j
= 5i + 9j
