Question

A rocket consumes 20 kg fuel per second. The
exhaust gases escape at a speed of 1000 ms-
relative to the rocket. Calculate the upthrust
received by the rocket. Also calculate the
velocity acquired. When its mass is 1/100 of
the initial mass. pls answer fastly answer will be 2(10^4) N and 4.6 km/s.. correct solution will be marked brainliest and wrong will be reported​

Solution

According to the problem the rocket consumes the fuel of 20 kg

The speed of the exhausting rate of gas is 1000 m/s

Now, dm/dt=20kg/s

u=1000m/s

As we know, upthrust =u(dm/dt)= 1000 x 20 20000 N

=1.536×105N

As v uloge(m0/m)

when the mass 1/100

then, v= 1000 loge (m0/m0/100)

v = 1000 x 2.303log10(100)

Required Answer

= 1000 x 2.303 × 2 m/s
