Q9. Inertia is the tendency of an object to resist any change in its motion.
Q10. A moving object's momentum depends on the object's mass and velocity.
Q11. I believe it would be air resistance. The fluid friction that opposes the motion of object's through the air.
Answer:
alright i responded

you didnt say i had to answer
<u><em>In accordance with the International Regulation for the prevention of collisions at sea</em></u><u>:

<u>1.- A sailing boat has a passing preference over a motorized boat, </u><u>except when the motor boat is limited by its draft</u><u>.
</u>
<u>2.- The sailboat must maintain its course and speed.
</u>
<u>3.- </u><em><u>If it is evident that the PWC does not respond</u></em><u>, the sailboat must sound the warning signal, and change its course to starboard.
</u>
<u>4.- </u><u><em>All actions must be taken as soon as possible</em></u><u>.
</u>
<u>5.- If a sailboat is using its engine, the situation changes, and in that case, both ships must alter to starboard.</u>
Answer:
v= 4055.08m/s
Explanation:
This is a problem that must be addressed through the laws of classical mechanics that concern Potential Gravitational Energy.
We know for definition that,
We must find the highest point and the lowest point to identify the change in energy, so
Point a)
The problem tells us that an object is dropped at a distance of h = 1.15134R over the earth.
That is to say that the energy of that object is equal to,
Point B )
We now use the average radius distance from the earth.
Then,
By the law of conservation of energy we know that,
clearing v,
Therefore the speed of the object when it strikes the Earth’s surface is 4055.08m/s
