Gravity is the force of attraction between two objects with mass.
Its strength depends on the mass of both masses, and on the
distance between them.
Democritus was the ancient greek atoms.
Answer:
t = 0.4 seconds
Explanation:
Given that,
Mass of the object, m = 2 kg
Initial speed of the object, u = 3 m/s
Finally, it stops, v = 0
Constant force applied to the object, F = 15 N
We know that,
Force, F = ma

So, it will take 0.4 seconds to stop the mass.
