mathphys may you me once again?

2. Same force; same impulse; Mini Cooper has greater change in velocity

4. Same momentum

6. It is distributed to the two halves

Explanation:

I will do the even problems as examples.

2. From Newton's third law, we know the bulldozer and Mini Cooper will experience equal but opposite forces.  So the magnitude of the force is the same.

Impulse is force times time.  Since the force is the same, and the amount of time is the same, then the impulse is the same.

Impulse is equal to change in momentum, or mass times change in velocity.  Since the Mini Cooper has the smaller mass, it has the greater change in velocity.

4. Momentum is mass times velocity.  The weight of the rover is different on Mars than on Earth, but the mass is still the same.  Therefore, if the rover moves at the same speed, it will have the same momentum.

6. The pencil's momentum is conserved.  When the pencil breaks in half, half the momentum goes to one half of the pencil, and half the momentum goes to the other half of the pencil.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
