Question

The expression known as​ Froude's number is given as Upper F equals StartFraction v squared Over gl EndFraction . This number was used in shipbuilding and also in research on dinosaurs. In this​ example, l is given as well as​ Froude's number. Find the​ velocity, v​ (in meters per​ second) of a rhinoceros. It is known that gequals9.8 meters per second squared. ​Rhinoceros: lequals​ 1.2; Froude number equals 2.6

Answer 1

Answer:$v=5.529\ m/s$

Explanation:

Given

number is given as $=\frac{v^2}{gl}$

and $number=2.6$

$l=1.2\ m$

g=acceleration due to gravity$(9.8\ m/s^2)$

calculating for $v$

$v^2=gl(2.6)$

$v=\sqrt{2.6\times 9.8\times 1.2}$

$v=\sqrt{30.576}$

$v=5.529\ m/s$
