What happens to the density of a given substance if you increase the amount of the substance that you have?
Amanda [17]
Have you ever looked up the density of a substance ?  You ought to try it.  Go ahead. Pick a substance, then go online or open up an actual book and find its density.  You will never see any particular volume mentioned along with the density . . . because it doesn't matter.  The whole idea of density is that it describes the substance, no matter how much or how little you have of it.  The density of a tiny drop of water under a microscope is the same as the density of a supertanker-ful of water.

A basketball player drops a 0.4-kg basketball vertically so that it is traveling at 5.7 m/s when it reaches the floor. The ball
Alik [6]

Answer:

(a) p = 3.4 kg-m/s (b) 37.78 N.

Explanation:

Mass of a basketball, m = 0.4 kg

Initial velocity of the ball, u = -5.7 m/s (as it comes down so it is negative)

It rebounds upward at a speed of 2.8 m/s  (as it rebounds so positive)

(a) Change in momentum = final momentum - initial momentum

p = m(v-u)

p = 0.4 (2.8-(-5.7))

p = 3.4 kg-m/s

(b) Impulse = change in momentum

Ft = 3.4

We have, t = 0.09 s

F=\dfrac{3.4}{0.09}\\\\F=37.78\ N

Hence, this is the required solution.
