The formula v=√64h gives the velocity v in feet per second of an object that has fallen h feet. Find the velocity of an object that has fallen 92 feet. Round to the nearest hundredth.
A) 13.56 feet/sec
B) 76.73 feet/sec
C) 54.26 feet/sec
D) 5888 feet/sec

Respuesta :

[tex]\bf v=\sqrt{64h}~~ \begin{cases} v=velocity\\ h=height\\ \cline{1-1} h=92 \end{cases}\implies v=\sqrt{(64)(92)}\implies v=\sqrt{5888} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill v\approx 76.73~\hfill[/tex]
