Question

A rocket is travelling at a speed of 500m/s. Ejects products of combustion at the speed of 1500m/s, relative to rocket . The speed of escaping vapours with respect to a person on earth is ​



please solve fast

Answer 1

Relative velocity V A/B = VA - VB

given V A/B =1500Km/h

VA - VB = 1500

VA −(−500)=1500

Since the velocity of combustion products and plane are in opposite directions

VA =1000km/h
