At what speed should a ball with a mass of 150 g fly so that its impulse is equal

At what speed should a ball with a mass of 150 g fly so that its impulse is equal to that of a bullet with a mass of 9 g flying at a speed of 500 m / s.

Problem data: m1 (ball mass) = 150 g; m2 (bullet weight) = 9 g; V2 (the speed at which the bullet flies) = 500 m / s.

Conversion of body masses into SI system is not required for calculation.

The speed of the ball is determined from the equality of impulses of the compared bodies: P1 = P2 = m1 * V1 = m2 * V2, whence V1 = m2 * V2 / m1.

Let’s make the calculations: V1 = m2 * V2 / m1 = 9 * 500/150 = 30 m / s.

Answer: The ball will have to fly at a speed of 30 m / s.
