A 12.4-g marble is dropped from rest onto the floor 1.56 m below. If the marble bounces straight upward to a height of 0.614 m, what is the magnitude of the impulse delivered to the marble by the floor

The impulse is    

Explanation:

Generally Impulse which the change in momentum  is mathematically represented as

Where m is the mass  with a value 12.4g =

            is the change in velocity which is mathematically represented as

Where s the velocity of the marble drooping and is the velocity of the marble bouncing back

setting up in a coordinate y-axis would show that is moving in the negative y-direction so the  value would be and   is moving in the positive  y-direction so the  value would be

So the formula for would be

General v i mathematically represented as

 Substituting this into the formula for

Now substituting values as given in the question

The impulse is

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
