We know that.
F = dp/dt.
dp = F*dt (where * is used here for multiplication).
Since here force and time is same so the change in momentum will be the same.
F = dp/dt.

Since here force and time is same so the change in momentum will be the same.

Momentum(p) = m*v.
p=f/a*v; since f=ma.
f=p/a*v; since a=v/t;.
f=p*t;.
Since time is constant, when we apply same force the momentum only changes.
p=f/a*v; since f=ma.
f=p/a*v; since a=v/t;.
f=p*t;.
Since time is constant, when we apply same force the momentum only changes.

Applied force is same.
Momentum=Mass*Velocity.
1st body velocity is high as mass is low.
2nd body velocity is low as mass is high.
Momentum=Mass*Velocity.
1st body velocity is high as mass is low.
2nd body velocity is low as mass is high.

Momentum.
m1 is not =to m2 but F2=F1 therefor m1a1=m2a2.
m1(vf1-vi1)/t=m2(vf2-vi2)/t;
vi=0.
m1vf1=m2vf2,
p1=p2.
m1 is not =to m2 but F2=F1 therefor m1a1=m2a2.
m1(vf1-vi1)/t=m2(vf2-vi2)/t;
vi=0.
m1vf1=m2vf2,
p1=p2.

This is according to the newton 2nd law of motion because according to this law force = Rate of change of momentum.

In this case momentum=m*v
Here v is 0 so if mass m1 is 3 and m2 is 4 but v is 0.
So momentum remains constant.
Here v is 0 so if mass m1 is 3 and m2 is 4 but v is 0.
So momentum remains constant.

Here the velocity, acceleration and momentum all will be same for both the objects. How it could be only momentum?

Force = rate of change in momentum over time.
f= p/t.
Therefore p=f*t as per newton second law of motion states.
f= p/t.
Therefore p=f*t as per newton second law of motion states.

Force=rate of change of momentum.
As force & time both are constant. So we get momentum=constant.
As force & time both are constant. So we get momentum=constant.

According to the newton second law the rate of change of momentum is equal to force.
