6N force pushes to the right on a 3 kg mass for 8 seconds. How much momentum was gained?
48kg*m/s
2kg*m/s
0.5kg*m/s
or 0kg*m/s
48kg*m/s
2kg*m/s
0.5kg*m/s
or 0kg*m/s

a = 2 m/s^2,
delta-v = 16 m/s,
delta-p = 48 kg*m/s.
OR: F = delta-p/delta-t =>
delta-p = F delta-t = (6N)/(8 s) = 48 kg*m/s

There's not enough information to determie how much momentum was gained. It could even be losing momentum.

ΔP = ΔI = 6 N * 8 sec = 48 N*sec = 48 kg*m/sec
ΔV = ΔP / m = 48 kg*m/sec / 3 kg = 16 m/sec
