C it is the energy required to break existing chemical bonds, it is the amount of energy that a reaction requires in order for the reactants to successfully collide and react
Answer:
A) 12.6 m/s2
B) -0.961 m
C) 0.961 m
D) 0.31 m/s
Explanation:
We can derive the acceleration function in term of t by taking 1st derivative of v(t)
The position function in term of t would be the integration of v(t)
Since s = 0 when t = 0 we can conclude that by plugging in t = 0 and s = 0
Part A: a(t = 3.1) = 6 - 6*3.1 = -12.6 m/s2. So the particle's deceleration is 12.6 m/s2 when t = 3.1
Part B:
Part C: As s(0) = 0 and s(3.1) = -0.961. The particle has traveled a distance of |-0.961 - 0| = 0.961m
Part D: So the particle has traveled a distance of 0.961m within time of 3.1s. That means the average speed is overall distance divided by overall time
= 0.961 / 3.1 = 0.31m/s

Image result for If the world was not tilted, what would happen to the people living on Earth
If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant
