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:

Based on the above situation, answer the following questions:

i. In the given figure, if √3 tan2θ – 3 = 0, where θ is acute angle, then find the value of θ.

(a) 45° (b) 30° (c) 60° (d) none of these

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

above) and be at a vertical height of 300 m?

(a) 300 m (b) 400m (c) 500 m (d) 600 m

iii. What should be the distance BC in order to pull the ship at the angle (calculated above) and be at a

vertical height of 300 m?

(a) 300√3 m (b) 400√3 m (c) 500√3 m (d) 600√3 m

iv. If BC = 100 m, θ = 60°, then AB is

(a) 100√3 m (b) 200√3 m (c) 500√3 m (d) 300√3 m

v. If the length of the rope, AC = 200m and θ = 30°, then the vertical height, AB is

(a) 300 m (b) 400m (c) 100 m (d) 200 m? ​
