Abstract. Abstract is defined as an idea or plan but no actions are done
to pursue the idea. When setting goals, one must be certain and it should be attainable in order
to achieve the goal being set. Goals that are abstract
are often poorly written and uncertain

The answer for this question is b because it says how far it goes before he begins to take brake
I think that this is false but I am not sure
Explanation:
Mass of the astronaut, m₁ = 170 kg
Speed of astronaut, v₁ = 2.25 m/s
mass of space capsule, m₂ = 2600 kg
Let v₂ is the speed of the space capsule. It can be calculated using the conservation of momentum as :
initial momentum = final momentum
Since, initial momentum is zero. So,



So, the change in speed of the space capsule is 0.17 m/s. Hence, this is the required solution.
