On an aircraft carrier, a jet can be catapulted from 0 to 240 km/h in 2.10 s. If the average force exerted by the catapult is 9.
Leya [2.2K]
<h2>Answer</h2>

The answer is 29495.3 kg

<h2>Explanation</h2>

As we know, the Newton's Second Law of Motion

Force = Mass * Acceleration

F = ma

The F exerted by catapult = 9.35 * 10^5

The Time is = 2.10 s

Velocity of the catapult = 240 km/h = 66.6 m/s   (240*1000 m /3600 s)

The mass of jet = ?

First detrmine the acceleration as

{/tex}Acceleration = Velocity/Time {/tex}

Acceleration = 66.6 ms^{-1}/2.1 s

Acceleration (a) =  31.7 ms^{-2}

Rearrange the formaula as

m= F/a

m= 9.35 * 10^5 N /31.7 ms^{-2}

m = 29495.3 kg

The mass will be 29495.3 kg

(ik it says physics but astronomy is a field of physics sooo) A recently discovered planet in a different solar system is locate
marusya05 [52]

The distance, to the nearest tenth, is 314.9 light-years.

<em>The given data is:</em>

A recently discovered planet is located 1.85*10^5 miles from Earth.

Now we want to transform this distance to light-years.

Remember that a light-year is defined as "the distance that the light would travel in one year".

using the relation:

distance = speed*time

The speed of light is:

speed = 6.706*10^8 mi/h

And in one year has 8760 hours, then we have:

time = 8760 h

replacing these in the equation we get:

distance = speed*time

distance = (6.706*10^8 mi/h)*(8760 h)  = 5,874,456,000,000 miles

Son one light-year is equivalent to 5,874,456,000,000 miles

1 light-year = 5,874,456,000,000 miles

So to transform a distance in miles to light-years, we just need to divide that distance by 5,874,456,000,000 miles:

The distance between the new planet and Earth was:

D = 1.85*10^15 mi = ( 1.85*10^15)/(5,874,456,000,000) = 314.9 light-years.

What shape does a position vs. time graph have for an object in uniform acceleration? a. quadratic b. cubic c. inverse d. linear
umka2103 [35]
Here, If acceleration is uniform, change is velocity will be uniform, and position-time graph represents for velocity, so it would be Linear

In short, Your Answer would be Option D

Hope this helps!
