Answer:
The plane would need to travel at least
(
.)
The
runway should be sufficient.
Explanation:
Convert unit of the the take-off velocity of this plane to
:
.
Initial velocity of the plane:
.
Take-off velocity of the plane
.
Let
denote the distance that the plane travelled along the runway. Since acceleration is constant but unknown, make use of the SUVAT equation
.
Notice that this equation does not require the value of acceleration. Rather, this equation make use of the fact that the distance travelled (under constant acceleration) is equal to duration
times average velocity
.
The distance that the plane need to cover would be:
.
Answer:
A- Greatest Kinetic Energy
B- Increasing Potential Energy
C- Increasing Kinetic Energy
D- Greatest Potential Energy
Explanation:
hope this is right.
Answer:
(c) more than 500
Explanation:
Until 2019, more than 3000 planetary systems have been discovered that contain more than 4000 exoplanets, since some of these systems contain multiple planets. Most known extrasolar planets are gas giants equal to or more massive than the planet Jupiter, with orbits very close to its star.
Answer:
Half
Explanation:
You only have to exert a force equal to half the weight of the load to lift it.
Answer: It would be 12 m/s.
Explanation: It would be this because If you go from rest to sprint it would be 12 m/s. Also, I did this the other day.
