1.	A rocket consumes 20 kg fuel per second. Theexhaust gases escape at a speed of 1000 ms-1relative to the rocket. Calculate the upthrustreceived by the rocket. Also calculate thevelocity acquired. When its mass is 1/100 ofthe initial mass.
Answer» ANSWER: UPTHRUST = mv/t = 20×1000 = 20000 N 1/100 of INITIAL mass = 20/100 kg/sec therefore, VELOCITY = 20000×100/20 = 100000 m/sec

Answer»

ANSWER:

UPTHRUST = mv/t

= 20×1000 = 20000 N

1/100 of INITIAL mass = 20/100 kg/sec

therefore,

VELOCITY = 20000×100/20 = 100000 m/sec
