Question
1. What forces does the Earth exert on the meteor DURING IMPACT? Select the best answer. Include a system schema and force diagram for the meteor
A. Gravity only
B. Contact force only
C. Contact force and gravity
D. Either contact force or gravity but not both (impossible to tell which).
2. If the meteor is coming to a very abrupt halt during impact, it must be accelerating.Which force has the greatest average magnitude during impact? Select the best answer.Showing work is optional (though you may want to modify your force diagram above.)
AThe gravity force has the greatest average magnitude during impact.
B. The contact force has the greatest average magnitude during impact.
C. Contact force and gravity have equal magnitudes during impact.
D. It is impossible to tell.
3. Select which object exerts greater force magnitudes on the other during this impact and why?
A. The meteor exerts a greater force magnitude on the Earth than the other way around, because the meteor is going faster than the Earth before impact.
B. The meteor exerts a greater force magnitude on the Earth than the other way around, becausethe meteor is more massive than the Earth.
C. The meteor exerts a greater force magnitude on the Earth than the other way around, becausethe meteor makes a giant crater in the Earth.
D. The Earth exerts a greater force magnitude on the meteor than the other way around, becausethe Earth is going faster than the meteor before impact.
E. The Earth exerts a greater force magnitude on the meteor than the other way around, becausethe Earth is more massive than the meteor.
F. The Earth exerts a greater force magnitude on the meteor than the other way around, becausethe Earth only has a crater while the meteor probably got ripped apart.
G. They exert equal-magnitude forces on each other because Newton’s 3rd law says this is alwaystrue for force interaction pairs between 2 objects.
H. They exert equal-magnitude force on each other because they accelerated the same and theyhave the same mass so they must have the same net force, according to Newton’s 2nd law.
4. Select which object experiences a greater acceleration (magnitude) during this impact andwhy? Remember to ignore everything else in the Universe except the Earth and the meteor.
i. The meteor has the greater acceleration magnitude because it applied a greater force magnitude on the Earth than the other way around.
ii. The meteor has the greater acceleration magnitude because it had the greater forcemagnitude applied to it by the Earth than the other way around.
iii. The meteor has the greater acceleration magnitude because it has an equal net force appliedto it by the Earth, as the Earth had by the meteor, but the meteor has less mass.
iv. The Earth has the greater acceleration magnitude because it applied a greater forcemagnitude on the meteor than the other way around.
v. The Earth has the greater acceleration magnitude because it had the greater force magnitudeapplied to it by the meteor than the other way around.
vi. The Earth has the greater acceleration magnitude because it has an equal net force appliedto it by the meteor, as the meteor had by the Earth, but the Earth has less mass.
(40 points total) A meteor with mass 3x1016 kg strikes the Earth, which has a mass of 24 kg. The former is an estimate of the mass of the impactor that struck Chicxulub, Yucatan, the most likely primary cause of the dinosaurs' extinction. Consider the Earth as including all parts (land, ocean, and atmosphere) in one object. Ignore everything else in the Universe except the Earth and the meteor.Explanation / Answer
The comit will experience gravitational force of the earth due to which it alters it's direction in the direction of force and it accelerates towards the earth during the impact there is contact force exerted by earth.
Option C both
