I've been stuck on this for i little bit now and could use some : )

The answer would be:

6,250 joules

Here's how to do it:

KE = kinetic energy (joules)

m = mass (kg)

v = velocity (m/s)

So with that formula let's figure out what was given to you.

500 kg and 5m/s

You know which is which based on the unit.

m = 500kg

v = 5m/s

Now all you need to do is plug it into your formula and solve.

The unit also means joules

So the final answer is 6,250 joules.

d i think its   answer d

explanation:

yes you are doing it right great gob
