A supply plane needs to drop a package of food to scientists working on a glacier in Greenland. The plane flies 110 m above the

zysi [14]

Answer:

The distance is 709.5 m.

Explanation:

Given that,

Speed = 150 m/s

Distance = 110 m

Suppose, How far short of the target should it drop the package?

We need to calculate the time

Using equation of motion

$s=ut+\dfrac{1}{2}gt^2$

$t^2=\dfrac{2s}{g}$

Where, g = acceleration due to gravity

t = time

Put the value into the formula

$t=\sqrt{\dfrac{2\times110}{9.8}}$

$t=4.73\ sec$

We need to calculate the distance

Using formula of distance

$d= vt$

Put the value into the formula

$d=150\times4.73$

$d=709.5\ m$

Hence, The distance is 709.5 m.

A woman standing on the ground sees a rocket ship move past her at 95% the speed of light. Compared to the rocket at rest, the w

Rufina [12.5K]

As per Einstein's theory of relativity we know that when an object will move with the speed comparable to the speed of light then the length of the object will be different from its length at rest position

This is also known as length contraction theory

As we know here that

$L = L_0\sqrt{1 - \frac{v^2}{c^2}}$

so here we know that

v = 0.95 c

so from above equation we will have

$L = L_0\sqrt{1 - 0.95^2}$

$L = 0.31 L_0$

so here the length will be SHORTER

Slove the following equation for v <br> A=v/t

LenKa [72]

If you meant solve, the answer would be v= A times t

You see, to get rid of an variable on one side, you must do the opposite of what is being done to it, in this case, multiply because division. After this, we must do what we did to one side to the other side. This creates the equation above!
