Answer:
The equation a=F/m or the acceleration is equal to the net force of an object divided by that object's mass, is an equation derived and explained by Sir Issac Newton's second law of motion. Newton's second law of motion states that the force of an object is equal to the mass times the acceleration of that object.
Net work = Work done - Amount Work release
W = 106 - 74 = 32 J
In short, Your Answer would be: Either C or D
Hope this helps!
Answer: Within any frame of reference that is accelerating
Special relativity was proposed on 1905 by Einstein, who developed his theory based on the following two postulates:
1. <em>The laws of physics are the same in all inertial systems. There is no preferential system.
</em>
2. <em>The speed of light in vacuum has the same value for all inertial systems.
</em>
Focusing on the first postulate, it can be affirmed that <u>any measurement on a body is made with reference to the system in which it is being measured</u>.
Now, taking into account that an inertial reference system is the one that complies with the principle of inertia:
<em>"For a body to have acceleration, an external force must act on it."</em>
The correct answer is
Within any frame of reference that is accelerating
<span>The American Southwest and northeastern Africa are the two sunniest regions of the world, with the U.S. city of Yuma, Arizona, taking the crown as the sunniest place on Earth. Yuma, located where the state borders both California and Mexico, receives more than 4,000 sunlight hours per year and averages 11 sunny hours per day over the course of the year. Following closely behind Yuma is another U.S. city -- Phoenix -- which receives an average of 3,872 sunlight hours a year. The third sunniest spot on Earth is Aswan, Egypt, which has an average of 3,863 sunlight hours every year and averages 10.6 sunny hours per day.</span>
The greatest height the ball will attain is 3.27 m
<h3>Data obtained from the question</h3>
- Initial velocity (u) = 8 m/s
- Final velocity (v) = 0 m/s (at maximum height)
- Acceleration due to gravity (g) = 9.8 m/s²
The maximum height to which the ball can attain can be obtained as follow:
v² = u² – 2gh (since the ball is going against gravity)
0² = 8² – (2 × 9.8 × h)
0 = 64 – 19.6h
Collect like terms
0 – 64 = –19.6h
–64 = –19.6h
Divide both side by –19.6
h = –64 / –19.6h
h = 3.27 m
Thus, the greatest height the ball can attain is 3.27 m
