The best approximation of the magnitude of the change in momentum of the object between 0s and 4 s is 40 kgm/s.
The change in the momentum of the object is determined from the impulse received by the object at the given period of time.
The change in momentum of the object is calculated as follows;
ΔP = Ft
where;
ΔP = Ft
ΔP = 10 x 4
ΔP = 40 Ns = 40 kgm/s
Thus, the best approximation of the magnitude of the change in momentum of the object between 0s and 4 s is 40 kgm/s.
