How this Option is Correct?- Practice Assignment 2 Question 7

[jayakrish...@gmail.com]

A plane begins to land when it is at a height of 1500 metre above the ground. It follows a straight line path and lands at a point which is at a horizontal distance of 2700 metre away. There are two towers which are at horizontal distances of 900 metre and 1800 metre away in the same direction as the landing point. Choose the correct option(s) regarding the plane’s trajectory and safe landing.

The trajectory of the path could bey27+x15=100y27+x15=100 if XX − axis and YY − axis are horizontal and vertical respectively

 The maximum safe height of the towers are 1000 metre and 1500 metre respectively.

The trajectory of the path could be y15+x27=100y15+x27=100 if XX − axis and YY − axis are horizontal and vertical respectively.

 The maximum safe height of the towers are 1500 metre and 500 metre respectively

 The maximum safe height of the towers are 1000 metre and 500 metre respectively

 None of the above.

How Option (E) is Correct. If the max. height of the towers are 1000m and 500m the plane will touch the both towers which are in planes path. So Correct is;- The maximum safe height of the towers are LESS THAN 1000 metre and 500 metre respectively
