Answer:
The correct answer is "625,000 J".
Explanation:
The given values are:
Mass,
m = 2,000 kg
Speed,
v = 25 m/sec
As we know,
⇒ [tex]Kinetic \ energy=\frac{1}{2} (mass \times speed^2)[/tex]
Or,
⇒ [tex]K.E=\frac{1}{2}(mv^2)[/tex]
On substituting the values, we get
⇒ [tex]=\frac{1}{2}(2,000\times 25^2)[/tex]
⇒ [tex]=1000\times 625[/tex]
⇒ [tex]=625,000 \ J[/tex]
