A 0.015 kg bullet is fired at a 1.5 kg block initially at rest. the bullet, moving with an initial speed of 500 m/s, emerges from the block with a speed of 400 m/s. What is the speed of the block after the collision?

What is the final velocity of the initial velocity of 25 and -50?

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as
