Question

A boy (25 kg) sits on a revolving chair (5 kg) holding a fire extinguisher (10 kg when empty and 20 kg with carbon dioxide). He points the discharge horn to the right and ejects 10 kg of carbon dioxide at 20 m/s. What is his speed and direction after the fire extinguisher is emptied (assuming friction is negligible)?​

Answer 1

Answer:

I TRIED IT BUT I THINK THERE ARE SOME MISSING VALUES IN IT ONLY IF IT HAD ACCELERATION OR DISTANCE OR TIME OF REVOLVING THEN IT WOULD HAVE BEEN EASY

I AM IN CLASS 9TH SO I DONT IF THERE IS ANY OTHER WAY OF SOLVING IT
