What speed will a motionless body with a mass of 5 kg acquire under the action of a force impulse of 20 N * s?

The law of conservation of momentum says that the momentum of a force is equal to the momentum of a body. The formula is written as follows:
F * t = m * V
Now we deduce the speed from this formula and substitute the values and that’s it, the problem is solved
V = F * t / m
F * t = 20 (H * c)
And it turns out
V = 20/5 = 4 (m / s)
Answer: V = 4 (m / s)
