Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 5.8 m/s2 for 3.3 seconds. It then continues at a constant speed for 9.8 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 255.79 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the blue car comes to a stop.3)How far does the blue car travel before its brakes are applied to slow down?

Answers

Well, the car gets to 5.8*3.3=19.14 m/s, getting to 5.8*3.3*3.3=63.162 meters from the start. For 9.8 secons it goes 187.572 meters, a total of 250.734. So, in 5.056 meters, it stopped uniformly. The speed dropped from 19.14 to 0 in 5.056 meters. There was a formula which didn't use time, but I've forgotten it. It would have given us the deceleration and then one could find the time through a 2nd degree equation. The timing for the first two parts is already known.
Either way, we've calculate more than we need to know for this question. You can cut the answer from that 250.734 distance.

While watching a recent science fiction movie, one Klingon spaceship blows up a Droid spaceship with a laser gun. The Klingon crew watches out the port window and covers their ears to muffle the noise from the explosion. Scientifically, this scene is inaccurate because A)
light can not reflect off objects in the vacuum of space.

B)
they would not be able to see anything outside the window.

C)
lasers can not be transmitted through the vacuum of space.

D)
the sound of the explosion would not be transmitted back to their ship.

Answers

Answer:

D) the sound of the explosion would not be transmitted back to their ship.

Explanation:

Sound is a mechanical wave. A mechanical wave requires a medium to travel and transfer energy. It travels be compression and rarefaction of the medium. Since in space it is vacuum, the sound energy by the explosion of the spaceship would not be able to travel through the space, the Klingon crew are not required to cover their ears to muffle the noise. This scene would be inaccurate scientifically.

D. is the right answer because his pressure is very bad out there in the air.good luck

Who gave us close up views of the gas giants and showed us their moons

Answers

Hi there!

The spacecraft widely known for it's beautiful images of the gas giants and its moons is the Voyager spacecraft (Voyager 1 & 2). The Voyagers took advantage of a rare opportunity in which all the gas giant planets were aligned that allowed them to get a gravity assist from each planet allowing for extremely close pictures and extremely high speeds on the spacecraft.

Copper has a specific heat of 0.385 j. A piece of copper absorbs 5000 J of energy and undergoes a temperature change from 100 Celsius to 200 degrees Celsius. What is the mass of the piece of copper?

Answers

The mass of the piece of copper will be 130 kg. In the International System of Units (SI), the kilogram is the unit of mass.

What is mass?

Mass is a numerical measure of inertia, which is a basic feature of all matter. It is, in effect, a body of matter's resistance to a change in speed or position caused by the application of a force.

The energy absorbed as;

$\rm \triangle E = mC \triangle t \n\n m = (\triangle E )/(mC) \n\n m = (5000 )/(0.385 (200-100)) \n\n m=130 \ kg$
