<h3><u>Full Question:</u></h3>
A 2-kg toy car accelerates from 5 to 10 m/s in 2 seconds. Find the applied force.
<h2><u>Answer:</u></h2>
Force applied is 
.
<h3><u>Explanation:</u></h3>
Force is defined as something which changes or tends to change the velocity of a body. And acceleration is defined as the rate of change of velocity of a body per time. Both of them are vector quantities.
The initial velocity of the body = 5 m/s.
The final velocity of the body = 10 m/s.
So the change in velocity = 10 - 5 m/s = 5m/s.
Time period = 2 seconds.
So acceleration =
= 
The force is defined as the product of mass and acceleration of the body.
Mass of body = 2 kg.
So, force applied = 
. =
.
Answer:
Explanation:
Given:
- mass of the object,
- weight of the object on planet x,
- radius of the planet,
- radial distance between the planet and the object,
<u>Now free fall acceleration on planet X:</u>
irrespective of the height.
Answer:
The answer is A
Explanation:
Being the force is acting upwards and displacement takes place horizontally
The correct answer is A. While the Big Bang is very possible it is still a theory. Even if you accept it, you have to see its flaws. Nothing is without flaw. There are many things it doesn't account for. Now, again this is not to say it is untrue just flawed. The best argument against it or anything similar would be that no one seen it happen.
