Answer:
3 m/s
Explanation:
The computation of speed is shown below:-
We will compute the equation by using the law of conservation of momentum; also, the total momentum prior and following the collision must be conserved. Therefore we can write the equation is the following manner:-
[tex]m_1 u_1 + m_2 u_2 = (m_1 +m_2)v[/tex]
where the symbols represent
150 kg is the mass of spaceship 1 = m1
150 kg is the mass of spaceship 2 = m2
0 m/s is the initial velocity of spaceship 1 = u1
6 m/s is the initial velocity of spaceship 2 = u2
and v is the velocity of the 2 ships so that they can collide and combined together
For v we will get the following equation to reach the speed
[tex]v=\frac{m_1 u_1 + m_2 u_2}{m_1+m_2}[/tex]
[tex]=\frac{0+(150)(6)}{150+150}[/tex]
[tex]=3 m/s[/tex]
