Question

Can anyone answer this question???

Answer 1

E = 216 joules

Explanation:

The given equation is

E =
`(m*v^(2) )/(2)` ............(i)

Here

m = 3 kg

v = 12 m/s

Putting the given values in equation (i)

E =
`(3*12^(2) )/(2)`

E =
`(3*144)/(2)`

E =
`(432)/(2)`

E = 216 kg m² /s²

or

E = 216 joules
