A projectile weighing 40kg flies at a speed of 400m / s. what is the impulse of the projectile?

The impulse will be equal to the product of the mass of the given projectile and its movement speed:

P = m * V, where, according to the condition of the problem, m (projectile mass) = 40 kg, V (projectile velocity) = 400 m / s.

Let’s perform the calculation:

P = 40 * 400 = 16000 kg * m / s.

Answer: The impulse of this projectile is 16000 kg * m / s.
