Question

when two same bodies are moving a slope which body will have more kinetic energy ?​

Answer 1

Answer:

Let m

1

and m

2

be the masses of the body

Let m

Given that

m

This shows the Kinetic energy is greater for that mass which is lighter

Answer 2

Answer:

$\huge\green{❥︎❥︎ANSWER}$

The kinetic energies are different, and the block on slope 1 has greater kinetic energy. Slope 1 is steeper, so the block gets to the bottom faster. Therefore it has a greater kinetic energy at the bottom. The kinetic energies are different, and the block on slope 2 has greater kinetic energy.
