If a screw falls off a light airplane from a height equal to the top of the empire state building (443 m), it hits the ground below after 9.50 s, assuming no air resistance. if the screw accelerates at 9.8 m/s2, how fast is it going when it hits the ground?

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
