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
If the object is kept in between the principle axis and the focus but some what nearer to the focus then we will get the enlarge,erect,and real image.
Two things are said to be in contact if the smallest distance between a point in one of them and a point in the other one is zero.
Answer:
D. move independently.
Explanation:
To be considered a living thing, an organism must be able to move independently.
