+69 A certain object traveling at 24 meters per second has a kinetic energy of 72 joules. If the kinetic energy of that object varies directly as the square of its velocity, find the kinetic energy of that object travelling at 27 m/s.
+36916 e = k v^2 k = proportionality 'k'onstant
72 = k (24^2)
k = 72 / (24^2) = 0.125
e = .125 v^2
e = .125 * 272 = 91.125 j
