Calculate the recoil velocity in the horizontal direction, in meters per second, of a 1.25-kg plunger that directly interacts with a 0.0175-kg bullet fired at 585 m/s from the gun. take the firing direction to be the positive direction.

'

Explanation:

It is given that,

Mass of the plunger,

Mass of the bullet,

Initially both plunger and the bullet are at rest,

Final speed of the bullet,

Let is the final speed of the plunger. Using the conservation of momentum to find it. The equation is as follows :

Since,

So, the recoil velocity of the plunger is 8.19 m/s. Hence, this is the required solution.

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

gans

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.
