Answer:
False?
Explanation:
Hope this helps you!
If this is wrong next time I will be better!
The mass of ball a is twice the mass of ball b:

This means that the initial potential energy of ball a (

) is twice the potential energy of ball b (

):

When the two balls reach the ground, the potential energy of each ball has converted into kinetic energy (since now their altitude is h=0), because the total mechanical energy of each ball must be conserved. Therefore:


and so the kinetic energy of ball a must be twice the kinetic energy of ball b:
Answer:
What is the definition magnitude?
Magnitude (mathematics), a measure of the size of a mathematical object.
