Answer:
The Total Momentum before and after collision remains the same.
Explanation:
Note that the balls have the same masses.
A moving cue ball has an initial momentum. After every collision with another stationary ball, the momentum, which is the product of their mass and velocity, of the balls is conserved. This simply means that the total momentum before the collision is the same as the total momentum after the collision.
This also means that the energy must be conserved as well. The balls cannot fling away from each other with more energy than you give them.

Answer:
<u>Box 1</u>
Explanation:
Formula we are using :
<u>Force = mass × acceleration</u>
or
<u>mass = Force / acceleration</u> (since mass needs to be found)
=============================================================
Box 1 :
⇒ mass = 5 N / 5 m/s²
⇒ mass = 1 kg
=========================================================
Box 2 :
⇒ mass = 5 N / 0.75 m/s²
⇒ mass = 5 × 4/3 = 20/3 kg
⇒ mass = 6.67 kg
===========================================================
Box 3 :
⇒ mass = 5 N / 4.3 m/s²
⇒ mass = 50/43 kg
⇒ mass = 1.16 kg
===========================================================
On comparing Box 1, Box 2, and Box 3, we understand that <u>Box 1</u> has the smallest mass
Answer:
A.
Mass per page = mass of book / number of pages
Mass per page = 2.5kg / 500 pages = 0.005kg
B.
Mass per page = mass of book / number of pages
Total mass = 2.5kg = 2,500grams = 2,500,000mili grams
Mass per page = 2500000mg / 500 pages = 5000mg
