That force DEcreases. This is a big part of the reason why the Earth attracts you with more force than Jupiter does.
Answer:
x-component of velocity = 5.7 m/s
y-component of velocity = -1.4 m/s
Explanation:
Use first equation of motion to find components of velocity at a given time:

where,
is the final velocity,
is the initial velocity,
is the acceleration and
is the time.
Given:



Mass is indirectly proportional to acceleration, so, lighter the object greater would be it's acceleration...
A) 0.10 kg is lightest among them, so it's your answer
