Explanation:
F=ma
a= v-u/t
F= m*v-u/t
3N= 2*v/3
u=o( initial speed)
v= 6/2
v=3km/s
v=3*18/5
v=54/5
v=10.8
May be in 3rd or 4th option
P=m*v
p= 3*10
p=30kgm/s

CONCISE PHYSICS (Numericals)
[Page - 67] [Answer - 6]
Given, Force (F) = 10 N
Mass (m) = 2 kg
Time (t) = 3 s
Let acceleration be "a".
(i) a = F/m = (10/2) m/s² = 5 m/s²
v = u+at = at = 15 m/s.
(ii) Change in momentum = m(v-u)
Or, ∆p = 30 kg m/s
THUS, YOUR QUESTION GETS SOLVED ENSURING AN APPROPRIATE PROCEDURE.
