In 542, the 2 is in the ones place. In 324, the 2 is in the tens place.
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
