The answer to this question is 106 m/s

m = mass = 5 kg

[tex] v_{i} [/tex] = initial velocity = 100 m/s

[tex] v_{f} [/tex] = final velocity = ?

I = impulse = 30 Ns

Using the impulse-change in momentum equation

I = m([tex] v_{f} [/tex] - [tex] v_{i} [/tex])

30 = 5 ([tex] v_{f} [/tex] - 100)

[tex] v_{f} [/tex] = 106 m/s
