Answer:

the question is quite basic

the formula for kinetic energy is

1/2mv²

we have

m=250kg

v=10m/s

taking the values in the formula we get

250×(10²)/2

250×100/2

now converting 250 kg in grams we get

250×1000

250000

thus 250000/2

125000joule is the required answer

Step-by-step explanation:

there i hope i help you
