PLEASE ANSWER
A 0.05 kg dart traveling 16 m/s hits a 0.15 kg movable target and sticks to it. How fast is the dart in the target moving together after the collision?

Explanation:
Conservation of Momentum
The more massive an object or faster object has more momentum as seen in the equation.
p = mv
The momentum of objects interacting get conserved. Many scenarios are covered in this section and many examples will represent interaction on a frictionless surface.
Throwing a Projectile
When a player throws a baseball, both the player and baseball start from rest. A baseball player throwing a baseball gains an equal and opposite momentum to the baseball thrown. In reality, friction keeps the player in one place after the throw. In space, a player would accelerate backwards every throw. The amount of acceleration is not as much since the baseball has little mass compared to the player.
Conservation of Momentum Equation
The conservation of momentum equation is not one set in stone. The momentum (p) of all the objects in a system before is equal to the momentum of those objects after. The scenario determines how you break out the conservation of momentum equation.
