Question

A Diwali rocket is ejecting 0.05 kg of gases per second at a velocity of 400 m s- 1 . The accelerating force on the rocket is (A) 20 dyne (B) 20 N (C) 22 dyne (D) 1000 N

Accelerating force on rocket due to ejecting gases F=u((d m/d t)) F=400× 0.05 F=20 N

Q. A Diwali rocket is ejecting $0.05 k g$ of gases per second at a velocity of $400 m s^{- 1}$ . The accelerating force on the rocket is

$20 d y n e$

$20 N$

$22 d y n e$

$1000 N$

Accelerating force on rocket due to ejecting gases
$F = u (\frac{d m}{d t})$
$F = 400 \times 0.05$
$F = 20 N$
