Answer:
4. both blocks will both have the same amount of kinetic energy.
Explanation:
When the blocks are released free from the compression force, the spring exerts equal and opposite force on each block but the block with heavier (double) mass will attain slower ( half ) speed as compared to the lighter block according to the law of inertia. This works in synchronization to energy conservation.
Spring force is given as:

where:
length of compression in the spring
<u>We know kinetic energy is given by:</u>

Hence the kinetic energy of both the blocks is equal when they are released to move free.
Answer:
i think D
hope this helps
let me know if i'm wrong i will change the answer
Explanation:
Answer:
if i am not mistaken the volume is 7, because it only took that much space
I would say d because the student isn’t moving, the Ferris wheel is.
Answer:
Gravity
because it's factorised by mass of a body.
For other forces, they deal with charges of negligible mass and weights
