Question

If a rocket has mass 1000 kg and fuel 500 kg then the force that the rocket experiences is

……………. if the exhaust is coming out at 100 meters per seconds ,and the fuel is

consumed at the 15 kg per second.​

Answer 1

Answer:

100kg-1

Explanation:

Given, the velocity of exhaust gases with respect to rocket =100ms-1

The minimum force on the rocket to lift it

Fmin = mg = 1000×10 = 10000N

Hence, minimum rate of burning of fuel is given by

dm/dt = Fmin/v

=10000/1000

=100kgs -1
