Answer:
Initial speed of the spaceship 1, v = 2 m/s
Explanation:
Given that :
Mass of spaceship 1 and 2 that have equal mass are 300 kg
Initial momentum of the spaceship 1 is 600 kg-m/s
To find :
We need to find the initial momentum of spaceship 1.
Solve :
The momentum of an object is equal to the product of mass and its velocity. Its SI unit is kg-m/s. Mathematically, it is given by :



v = 2 m/s
Therefore the initial speed of spaceship 1 is 2 m/s. Hence, this is the required solution.
Answer:
40.22 days
Explanation:
Given data:
Closest approach distance between Mars and Earth = 56 million km = 56 × 10⁶ km
Speed of the spaceship = 58000 km/h
Now, the time (t) is calculated as:
time = Distance / speed
on substituting the values, we get
t = 56 × 10⁶ km / (58000 km/h)
or
t = 965.517 hours
or
t = 965.517 / 24 days = 40.22 days
