The work done by the shark is 128000 J which is greater than the maximum force the cage can withstand (124500 J), the man in the cage should be worried.
<h3>What is work done?</h3>
Work done is the product of force and the distance covered by the force.
Mathematically;
- Work done = Force × distance
The unit of work done is Joules.
The work done by the shark is calculated as follows:
Work done = 12800 × 10
Work done = 128000 J
Maximum force the can withstand = 124500 J
Since the work done by the shark is greater than the maximum force the cage can withstand, the man in th cage should be worried.
