This would be most representative of Newton’s first law of motion, an object will continuously move in a straight line at constant velocity until a force is applied on to the object.
Answer:
Explanation:
For loop-the-loop, to stay at the top of the loop the centripetal force must equal the gravitational force
solving for velocity we get:
Thus, the minimum kinetic energy required is
Answer:
Explanation:
first pilot moved 62.6 miles west towards another airport
so we have
now at that airport it fly again 28.9 miles at 15 East of South
so we have
now net displacement of the plane is given as
magnitude of the displacement is given as
<span>So we want to know what happens to meteors that enter the Earth's atmosphere and experience air friction. So since most meteors that enter Earth's atmosphere are made out of ice and/or rocks, when they enter the atmosphere, they experience air friction and their temperature rises so high they either melt or burn up. So the correct answer is burns up. </span>
