An engine water continuously through a hose. Water leaves the hose with a velocity v and m is the mass per unit length of the kinetic energy is imparted to water ?

Options

A. `(1)/(2)mv^(2)`
B. `mv^(3)`
C. `(3)/(2)mv^(2)`
D. `(5)/(2)mv^(2)`

Answer

A, B, C

Explanation

m = Mass per unit length
[for per second `V=("distance")/("time"),t=1s`, V = distance]
`therefore` Mass of water flowing per second = mv
`K.E=(1)/(2)(mv)xxv^(2)`
`=(1)/(2)mv^(3)`
