What condition alone is necessary so that the final kinetic energy of the system is zero after the collision?
<u>Option(a). </u>The objects must have initial momenta with the same magnitude but opposite directions.
What is a momentum?
- In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object.
- It is a vector quantity, possessing a magnitude and a direction.
- If m is an object's mass and v is its velocity (also a vector quantity), then the object's momentum p is :p=mv.
- In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.

Answer:
How do you find out the missing masses in a balloon?
Well, actually you can't find the missing masses in a balloon. Why?
Because the mass of the mass of balloon, it can't see the mass of it, it only see if it the balloon is deflated or inflated.

Explanation:
As we know that tank itself has mass given as 13.4 kg
so it is given as
also the tank contains air in it and the mass of air inside the tank is also given as 4.47 kg
so it is
so total mass of the tank is the mass of the empty tank and mass of air in the tank
