6. A journalist is testing the acceleration of a new car. He measures the final velocity of the car to be 15 m/s. If the
car was initially stopped 10 s before the journalist made her measurement, what is the car's acceleration?

Answers

Answer 1

Answer:

1.5 m/s^2

Explanation:

Don't rlly understand the question, but I'll just take it as the initial velocity is 0

a = 15 - 0

What is the goal of a theory?

Answers

Hi,

The goal of a theory is to explain natural and physical phenomena.

Hope it helps you...

Pls mark brainliest if it helps you...

(Answered by Benjemin)

We can define theory as:

"A logical-deductive or inductive and organized set of ideas that explain a given phenomenon, where the deductions are based on observations".

With this, we can see that the correct option is "To explain natural and physical phenomena"

Now let's explain this a little bit more.

Here we want to see the goal of a theory.

So, what is the end of a theory?

A theory wants to explain something. Someone sees a phenomenon, and in a need to understand it, uses the information that he/she has to try to explain it. Then he/she proceeds to do experiments to test if the theory is correct.

Concluding, the correct option is:

"To explain natural and physical phenomena"

Bobo, the clown, wants to set the world record for the furthest range traveled by a clown shot out of a cannon. Write a sentence describing the cannon that Bobo would need to use to accomplish this feat. Be sure to include the necessary initial velocity and the required angle of the cannon. Score: 0 / 1

Answers

In the human cannonball act makes use of of a special type of "cannon" that more safely ejects a person who acts as the "cannonball"

The world record for the longest flight by a human cannonball is approximately 194 feet and therefore the human cannon catapult that Bobo would need is one that would be able to propel him with an initial velocity of more than 120 kilometer per hour (more than the speed of the current record holder) with the cannon directed at an angle 45 degrees above the horizonal

The reason the values given above are correct is as follows:

The world record of the furthest range of the human cannonball is 193 ft. 8.8 inches. The maximum claim for the furthest range of a human cannonball is 200 ft. 4 in. Therefore, to safely set the world record would be to reach a range of 194 feet

The speed with which the world record was accomplished (120 km/jhr)  should be expected to be exceeded given, horizontal speed in free fall motion is constant (decreasing in the presence of drag), and the conditions are likely to be more or less similar

In order to reach the furthest range, R, at the possible speed, the angle of inclination of the "cannon" required is 45°, according to the range formula, which is given as follows;

[tex]Range, \ R = \dfrac{v^2 \times sin(2\cdot \theta)}{g}[/tex]

The maximum range is given where θ = 45, such that sin(2·θ) = sin(90°) = 1

A further range than the world record van be obtained using the above values

state Newton's laws of motion​

Answers

Answer:

Newtons First Law (The Law of Inertia)- If an object is at rest it will stay at rest until a net force acts on it. If an object is in motion it will stay in motion until a net force acts on it.

Newtons Second Law (F=ma)- Force equals the mass of an object times it's acceleration.

Newton's Third Law- For every action there is an equal and opposite reaction.

hope this helps!

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction

If Scoobie could drive a Jetson's flying car at a constant speed of 160.0 km/hr across oceans and space, approximately how long would Scoobie take to drive around Earth's equator in days

Answers

Your first step is to find the circumference of the earth, with the numbers given. You can do that by putting the radius of 6200 kilometres into the 2πr equation. That should get you a circumference of 12400π, or about 38,955.75 kilometres.

Next, you can use the rate the Jetson's car is going (180km/h) and divide the 38,955.75 by it to see how many hours it would take at that constant speed.

38,955.75 / 180 = 216.42 hours

Then you can divide that by 24 to get how many days

Answers

Yes.

The acceleration vector WILL point south when the car is slowing down while traveling north

When a car is traveling north, its acceleration vector can point south when it is slowing down.

A vector quantity has both magnitude and direction. The direction of a vector is always shown by the direction to which the arrow points.

If the car is travelling north, the direction of the acceleration vector will continue to point northwards.

However, when the car slows down, the direction of the accelerating vector will now point southwards.

what is work - energy theorem ??​

Answers

The work-energy theorem explains the idea that the net work - the total work done by all the forces combined - done on an object is equal to the change in the kinetic energy of the object. After the net force is removed (no more work is being done) the object's total energy is altered as a result of the work that was done.

This idea is expressed in the following equation:

is the total work done

is the change in kinetic energy

is the final kinetic energy
