Imagine you are ice skating with your BFF. Both of you are at rest in the middle of the ice, when you shove your BFF away from you. You have a mass of 70 kg and your BFF has a mass of 60kg. When you shove off, you are moving with a velocity of 2.5 m/s. What should the total net momentum be after the push?

The total net momentum after the push is 0.

Explanation:

The total net momentum is given by:

Where:

m₁: is the mass of 70 kg

m₂: is the mass of 60 kg

v₁: is the speed of 2.5 m/s

v₂:?

To find the final momentum first we need to find the speed v₂:

Where is the initial momentum = 0 (they are at rest)          

The minus sign is because the second person is moving in the opposite direction to the first person.

Now, the total net momentum is:

The final total momentum (after the push) should be zero because of momentum conservation.

Therefore, the total net momentum after the push is 0.

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

i need the answer to this too but idk it ; -;
