Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that initially the two blocks are connected by a spring and initially stretched by some amount
Since the two blocks are at rest initially so its initial momentum is zero
since there is no external force on this system so final momentum is also zero
now for initial position the speed is zero
now we have
Part b)
now for ratio of kinetic energy we know that the relation between kinetic energy and momentum is given as
now for the ratio of energy we have
since we know that momentum of two blocks are equal in magnitude so we have
now we have
Answer:
The __law__ conservation
of state that either energy may produced nor destroyed

Thank you so much!!!!

I really need this points
Rigidbodies are components that allow a GameObject<u> to react to real-time physics. </u>
Explanation:
- Rigidbodies are components that allow a GameObject to react to real-time physics. This includes reactions to forces and gravity, mass, drag and momentum. You can attach a Rigidbody to your GameObject by simply clicking on Add Component and typing in Rigidbody2D in the search field.
- A rigidbody is a property, which, when added to any object, allows it to interact with a lot of fundamental physics behaviour, like forces and acceleration. You use rigidbodies on anything that you want to have mass in your game.
- You can indeed have a collider with no rigidbody. If there's no rigidbody then Unity assumes the object is static, non-moving.
- If you had a game with only two objects in it, and both move kinematically, in theory you would only need a rigidbody on one of them, even though they both move.
Answer:
not true because the mass from the heavy car will cause it to damage more
