First, calculate the acceleration of the bullet by making use of the second law of motion by Newton which can be translated in equation as,

F = m x a

Solving for a,

a = F/m

Substituting the known values,

a = (200 N) / (0.025 kg) = 8000 m/s²

The maximum velocity of the bullet is the product of the acceleration and the given time.

v = (8000 m/s²) (0.1 s) = 800 m/s

Answer: 800 m/s
