Question

‘Skysails’ is that genre of engineering science that uses extensive utilization of wind

energy to move a vessel in the sea water. The ‘Skysails’ technology allows the towing

kite to gain a height of anything between 100 metres – 300 metres.

The sailing kite is made in such a way that it can be raised to its proper elevation and

then brought back with the help of a ‘telescopic mast’ that enables the kite to be raised

properly and effectively.

Based on the following figure related to sky sailing, answer the questions:


(i) In the given figure, if sin ߠ = cos (3ߠ − 30଴

), where ߠ and 3ߠ − 30଴ are acute
angles, then find the value of ߠ.


(ii) What should be the length of the rope of the kite sail in order to pull the ship at

the angle ߠ) calculated above) and be at a vertical height of 200 m?​

Answer:

It’s pretty obvious that we should be grateful to the “essential workers” during this time of shelter in

place. Food suppliers, health care workers, delivery people, and first responders have taken on risks to

themselves for the benefit of everyone else. How can we possibly repay them? By showing a littlm
