Study Case : Q. 11 to 15

SLV-3 was successfully launched on July 18, 1980 from Sriharikota Range (SHAR), when Rohini Satellite, RS-1, was placed in orbit, thereby making India the sixth member of an exclusive club of space-faring nations.

SLV-3 employed an open loop guidance (with stored pitch programme) to steer the vehicle in flight along a predetermined trajectory. The successful culmination of the SLV-3 project showed the way to advanced launch vehicle projects such as the Augmented Satellite Launch Vehicle (ASLV), Polar Satellite Launch Vehicle (PSLV) and

Geosynchronous Satellite Launch Vehicle (GSLV) Students of Class-Xth made a mathematical model of a rocket as shown in the figure below:

Based on the above information give the answer of the following questions:

The coordinates of the point A are:

A) \[(4,9)\]

B) \[(5,9)\]

C) \[\left( \frac{9}{2},9 \right)\]

D) \[(4,8)\]

Correct Answer: C

Solution :

As the distance of point A is \[\frac{9}{2}\] units from the Y-axis and 9 units from the X-axis, its coordinates are

\[x=\frac{9}{2},\] \[y=9\] or \[\left( \frac{9}{2},9 \right)\]

So, option [c] is correct.
