10.A 600 kg great white shark is lurking below an observation cage. His movement is
Nadya [2.5K]

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.
