Diwali rocket is ejecting 50 g of gases $/ s$ at a velocity of $400 m / s$ . The accelerating force on the rocket will be

Options:

Answer:

Solution:

The accelerating force on the rocket $= upward thrust = \frac{Δ m}{Δ t} \cdot u$ Given, $\frac{Δ m}{Δ t} = 50 \times 1 0^{- 3} kg / s, v = 400 m / s$ So, accelerating force $= 50 \times 1 0^{- 3} \times 400$ $= 20 N$
