A rocket, which consists of two parts or stages, is travelling at 8.80 km/s. The first stage of the rocket, which has an approximate mass of 856 kg is ejected from the second stage and it will travels at 4.80 km/s. The second stage of the rocket has a mass of 468 kg. What is the velocity of the second stage just after the first stage is released? Give your answer in km/s to 2 decimal places

Question

A rocket, which consists of two parts or stages, is travelling at 8.80 km/s. The first stage of the rocket, which has an approximate mass of 856 kg is ejected from the second stage and it will travels at 4.80 km/s. The second stage of the rocket has a mass of 468 kg. What is the velocity of the second stage just after the first stage is released? Give your answer in km/s to 2 decimal places

Expert Solution
Given data :-

A rocket travelling, which has two parts. One part gets released. 

Mass of first part, m1 = 468 kg

Mass of second part, m= 856 kg

Initial velocity of rocket , u = 8.80 km/s

Velocity of part that gets released, v2 = 4.80 km/s

Velocity of part that remains, v1 = ?
