Question

Can anyone answer this question???

Answer 1

Answer:

E = 216 joules

Step-by-step explanation:

The given equation is

E = $\frac{m*v^{2} }{2}$                ............(i)

Here

m = 3 kg

v = 12 m/s

Putting the given values in equation (i)

E = $\frac{3*12^{2} }{2}$

E = $\frac{3*144}{2}$

E = $\frac{432}{2}$

E = 216 kg m² /s²

or

E = 216 joules
