Fig. 2.1 depicts a space vehicle made up of a capsule and a nose cone. The space vehicle is travelling with a velocity of $7800\,\text{m\,s}^{-1}$. Its mass is $840\,\text{kg}$.
(a)[1]
Show that the momentum of the space vehicle is about $6.55 \times 10^{6}\,\text{kg\,m\,s}^{-1}$.
(b)[3]
Calculate the velocity $v$ of the capsule after the nose cone has been ejected. Give your answer to 3 significant figures.
(c)[2]
Calculate the mass of the capsule.
