The angle of elevation of a jet plane ...

The angle of elevation of a jet plane from a point `A` on the ground
is `60^@` . After a flight of 30 seconds, the angle of elevation changes
to `30^@` . If the jet plane is flying at a constant height of `3600sqrt(3)m`,
find the speed of the jet plane.

Text Solution

Verified by Experts
