Base elevation is 1250 ft
rate is 30 per minute 30m
so, h = 1250 - 30m
as an inclusion, 30 ft per minute is also like 0.5 per second like 1250 - 0.5s
1250/30 means it would be about 42 minutes once it touches the ground.
By definition, the formula of the period of a pendulum is given by:
From here, we must clear the value of l.
We have then:
Raising both members to the square we have:
Then, passing gravity to multiply, we have:
Answer:
When clearing we have:
Answer:
The sum of 3 consecutiveodd number is 27. What are the 3 numbers?
Step-by-step explanation:
Answer:
1.6 meters per second.
Step-by-step explanation:
We have been given an position function
and we are asked to find the speed of the rock after 1 second.
Derivative of this function will give us speed function.
![S(t)=2\cdot 0.8\cdot t](https://tex.z-dn.net/?f=S%28t%29%3D2%5Ccdot%200.8%5Ccdot%20t)
![S(t)=1.6\cdot t](https://tex.z-dn.net/?f=S%28t%29%3D1.6%5Ccdot%20t)
Now let us find derivative when t=1,
![S(1)=1.6\cdot 1=1.6](https://tex.z-dn.net/?f=S%281%29%3D1.6%5Ccdot%201%3D1.6)
Therefore, the speed of the rock after 1 second will be 1.6 meters per second.
