If a construction worker drops a wrench
from the top of a building 375 feet high the
wrench will be
s(t) = −16t2 + 375
feet above the ground after t seconds.
determine the velocity of the wrench 4 seonds after it was was dropped.

answer in units of ft/sec

To find velocity at a given moment, also known as instantaneous velocity, we need to know how to take the derivative of an equation;
you can take the derivative of s(t)=62t^2+ 375 by first moving the 2 in front of 162 and multiply both which well give you 324t and 375 will turn to 0
-16t^2 results in -32t
so our velocity at t=4 is -32(4) = -128ft per second

Indoraptor for sure

Following the american gauge wire standards ,the larger gauge number, the slimmer the wire and thus the smaller current carrying capacity it can have.then both statements would be incorrect, as they are saying the opposite of what it is actually is.(smaller gauge numbers have thicker wires and can carry more current)
