Answer:
96 ft/s
Step-by-step explanation:
We can start by deriving the equation of the velocity, which is the derivative of the position equation:
![v(t) = \frac{ds}{dt} = (-16t^2)' + 800' = -32t](https://tex.z-dn.net/?f=v%28t%29%20%3D%20%5Cfrac%7Bds%7D%7Bdt%7D%20%3D%20%28-16t%5E2%29%27%20%2B%20800%27%20%3D%20-32t)
After 3 seconds, the wrench would achieve a speed of
v(3) = -32t = -32*3 = -96 ft/s
So it's falling at the rate of 96 ft per second after 3 s

Answer:
The value of n is 5
Step-by-step explanation:
Here, we want to get the value of n
To get this, we will need to use the appropriate trigonometric identity
As we can see, n represents the opposite as it the side that faces the angle given
m is the hypotenuse as it is the side that faces the right angle
The last side is called the adjacent
The trigonometric identity we want to use is that which connects the opposite to the adjacent
The appropriate trigonometric identity to use in this case is the tan
Thus;
Mathematically, the tan is the ratio of the opposite to the adjacent
hence;
tan 30 = n/ 5 √3
n = 5 √3 * 1/ √3
n = 5
