Displacement vectors of 10 m west and 14 m west make a resultant vector that is _____.

Anastaziya [24]

For this case we can write each one of the vectors in the following way:

$v1 = 10 i\\v2 = 14 i$

This means that the x-axis is defined as positive towards the west.

Then, the resulting vector is:

$v1 + v2 = 10i + 14i\\v1 + v2 = 24 i$

Answer:

Displacement vectors of 10 m west and 14 m west make a resultant vector that is 24 m west

An elephant and a mouse would both have zero weight in gravity-free space. If they were moving toward you with the same speed, w

Dovator [93]

The elephant and the mouse having zero weight in a gravity free space will not bump into you at the same effect.

<u>Explanation: </u>

When both are in a gravity free space, the weights are zero, as we know that the $\text {weight of the body}=\text {mass of the body} \times \text {acceleration due to gravity}$

$\text {here, the weight of elephant}=\text {mass of elephant } \times \text {zero gravti} y=zero$

$\text {similarly,weight of mouse}=\text {mass of mouse } \times \text {zero gravity}=zero$

But when they will acquire the speed of same magnitude, say v, their different masses will acquire different momentum, which will make the difference in effect while bumping.

$\text { momentum of elephant }=\text { mass of elephant } \times v$ $\text { momentum of mouse = mass of mouse } \times v$

And as we know $\text { mass of elephant }>\text { mass of mouse }$ Therefore, effect of impact by elephant will be more than that of mouse . An elephant breaking into you will take you back faster than a mouse in space hits you.
