Mass is a property of the object. It doesn't depend on anything else,
and it doesn't change when the object goes to different places.
Its mass is always the same.
If it's 20,000 kilograms on Earth, then it's 20,000 kilograms on the
Moon, on Mars, in school, in bed, in love, in trouble, in water,
on Pluto, on Halley's comet, or in free fall in outer space.
That's why choice-B is the correct choice.
Now, if the question was talking about WEIGHT, then we would have
a lot to talk about, because WEIGHT depends on where you are, and
what else is around you. But mass doesn't.
The acceleration is -1.111 m/s²
Explanation:
In this case acceleration is calculated as change in velocity divided by time.
Change in velocity is 20m/s-120 m/s = -100 m/s
Time is 1.5 minutes------change it to seconds by multiplying 1.5 by 60 seconds
Acceleration will be : -100 m/s / (1.5*60) = -1.111 m/s²
