0.4 x 18 = 7.2 kg m/s
The momentum of the bottle after being hit is 0.2 x 25 = 5 kg m/s
7.2 - 5 = 2.2 kg m/s is the motmentum of the ball now
the velocity is 2.2/0.4 = 5.5 m/s
Answer:
C
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces
I hope this helps a little bit
Answer:
denoting, relating to, or operated by a liquid moving in a confined space under pressure.
a substance's density is the same at a certain pressure and temperature, and the density of one substance is usually different than another substance.
The first collision because a greater amount of momentum must be taken and used in order to push the cart back, giving it a greater mass and impulse
