Answer:

700 Joules

Step-by-step explanation:

The work done equals force times distance. Just multiply your two values there.

Side note: It would be more impressive if he'd done it in 1 second rather than 5. You know why? Because POWER=WORK/TIME. The less time it takes him to lift the weight with the same force and distance, the more powerful he is!
