Question

A rocket burns 0.4 kg of fuel per sec and ejectas gas 8 kmper s find force

Answer 1

$\mathfrak{\huge{\pink{\underline{\underline{AnswEr :}}}}}$

⚘Mass = 2kg

⚘Velocity = 80km/s = 80000 m/s

⚘ Force = mu

= m × (v - u)/t

= 2 × 80000

= 160000N

Answer 2

$\huge\underline\mathcal{Answer}$

⭑A rocket burns 0.4 kg of fuel per sec and ejectas gas 8 kmper s find force:-

⭒Mass = 2kg

Velocity = 80km/s = 80000 m/s
