Problem 1. (20 pts)
The third and fourth stages of a rocket are coastin
in space with a velocity of 18 000 km/h when a smal
explosive charge between the stages separate
them. Immediately after separation the fourth stag
has increased its velocity to v4 = 18 060 km/h. Wha
is the corresponding velocity v3 of the third stage
At separation the third and fourth stages hav
masses of 400 and 200 kg, respectively.
