Answer:
Wohhh thanks for you free answer. Well i will be appreciating it.
Work done = Force X Distance
3 430 000J = Force X 14m
Force = 3 430 000J / 14m
= 245 000 N
Hope this helps!
Answer:
The value is 
Explanation:
From the question we are told that
The velocity is ![a = 120 \ km/h = [tex]\frac{120 * 1000}{3600} = 33.3 \ m/s](https://tex.z-dn.net/?f=a%20%3D%20%20120%20%5C%20%20km%2Fh%20%3D%20%20%5Btex%5D%5Cfrac%7B120%20%2A%20%201000%7D%7B3600%7D%20%3D%20%2033.3%20%5C%20%20m%2Fs)
[/tex]
The time taken is 
The time taken for contact is 
The velocity of the of the car after contact is ![v_c = 71.0 \ km/h = [tex]\frac{71 *1000}{3600} = 19.7 2 \ m/s](https://tex.z-dn.net/?f=v_c%20%3D%20%2071.0%20%5C%20%20km%2Fh%20%3D%20%5Btex%5D%5Cfrac%7B71%20%2A1000%7D%7B3600%7D%20%3D%20%2019.7%202%20%5C%20%20m%2Fs)
[/tex]
From the equation of kinematics we have that
Here u = 0 \ m/s since the car is initially motionless

He values artistic success over financial success for himself.
He believes most people benefited from losing their financial stability.
He regrets the fact that he gave away his money to benefit his art.
Explanation:
Answer:
Natalie says that all things with mass have a gravitational field, but the force is very weak and cannot be perceived around small objects.
Explanation:
The force due to gravity is proportional to the mass of the object and inversely proportional to the square of the distance between objects. The Earth is so massive that the force due to its gravity is much greater than the force between objects on the counter.
If there were no friction, the objects might move toward each other, depending on what other masses were near them tending to cause them to move in other directions.
Natalie's explanation is about the best.

<em>Additional comment</em>
The universal gravitational constant was determined by Henry Cavendish in the late 18th century using lead balls weighing 1.6 pounds and 348 pounds. His experiment was enclosed in a large wooden box to minimize outside effects. While these masses are somewhat greater than those of a glue bottle and stapler, the experiment shows the force of gravity between "small" objects <em>can</em> be measured.
