Question

a jet airplane travelling at the speed of 500 km per hour ajax its products of combustion at the speed of 1500 km per hour relative to the jet. What is the speed of the letter with respect to an observer on the ground ​

Answer 1

Answer:

first u take me in the jet then will give answer there it self

Answer 2

Answer:

Speed of the jet airplane, v jet = 500 km/h

Relative speed of its products of combustion with respect to the plane,

v smoke = – 1500 km/h

Speed of its products of combustion with respect to the ground = v′smoke

Relative speed of its products of combustion with respect to the airplane,

vsmoke = v′smoke – vjet

1500 = v′smoke – 500

v′smoke = – 1000 km/h

The negative sign indicates that the direction of its products of combustion is opposite to the direction of motion of the jet airplane.
