A rocket is gong upwards with acceleratedmotion. A man sitting in it feels his weightincreased 5 times his own weight. If the massof the rocket including that of the man is1.0x104kg, how much force is being applied byrocket engine? (Take g = 10 ms 2)5x104N5x10ʻN5x10'N(0 O2x10*N​

Answer»

GIVEN:

Total MASS(man+rocket), m` =1.0×10⁴ kg

Now:

The mass of man sitting in the rocket is INCREASED by 5 times.

As force due to mass = mg,

\tt\pink{So,  a = 5g = 5 × 10 = 50m/s²}

.

Force applied by the rocket engine,

\tt\red{F=ma=1.0×10⁴ ×50=5×10^5 N}
