what is resultant velocity?

Question

give me a example.

Answer 1

Example: you walk on a cart in direction north at 2 mph. Meanwhile, the cart moves over the deck of a ship at 10 mph in direction east. The ship, in turn, moves at 4 mph in direction west relative to the water; and the water at 2 mph south relative to the shore. Question: what is your speed relative to the shore?

Answer: the "resultant" velocity is the sum of all velocities involved. We split out horizontal and vertical components and add:

N-S direction: 2 + 0 + 0 - 2 = 0 mph
E-W direction: 0 + 10 - 4 + 0 = 6 mph

So the resultant velocity is 6 mph east.

Answer 3

resultant velocity

Answer 4

In all such cases, the resultant vector (whether a displacement vector, force vector, velocity vector, etc.) is the result of adding the individual vectors. It is the same thing as adding A + B + C + ... . "To do A + B + C is the same as to do R." As an example, consider a football player who gets hit simultaneously by three players on the opposing team (players A. B. and C). The football player experiences three different applied forces. Each applied force contributes to a total or resulting force. If the three forces are added together using methods of vector addition (discussed earlier), then the resultant vector R can be determined. In this case, to experience the three forces A, B and C is the same as experiencing force R. To be hit by players A, B, and C would result in the same force as being hit by one player applying force R. "To do A + B + C is the same as to do R." Vector R is the same result as vector A + B + C!!
