Answer:
Distance moved, s = 2 meters
Explanation:
It is given that,
Net force acting on object, F = 1 N
Mass of object, m = 4 kg
We have to find the distance moved by object during 4 seconds.
From Newton's second law : 

Using second equation of motion to find distance :

s is distance, u = 0 because initially the object is at rest


s = 2 m
Hence, the distance moved by particle in 4 seconds is 2 meters.
