Answer:
2 m/s
Explanation: Given that a flatbed car of a train moves 8 m/s to the east. A jogger runs along to top the flatbed car (which is not very safe) with a velocity of 6 m/s to the west.
Since the jogger is moving in an opposite direction to the direction of the train, and velocity is the distance covered in a specific direction, the jogger will be moving at a velocity relative to the velocity of the train.
Velocity = (8 - 6) m/s
Velocity = 2 m/s
Therefore, the jogger will be moving at the speed of 2 m/s

Mass of Derrick at a height 4.3 m having 2730 joule of energy is 65 Kg.
<h3>What is the expression of gravitational potential energy near the earth surface?</h3>
- Mathematically, gravitational potential energy near the earth surface= m×g×h
- m= mass of Derrick, g= acceleration due to gravity, h= height at which Derrick present
- Then, mass (m) of Derrick = potential energy/ (g×h)
<h3>What is the mass of Derrick, if he gains 2730 joule of energy at 4.3m above the ground?</h3>
Mass of Derrick= 2730/(9.8×4.3)
= 65 kg
Thus, we can conclude that the mass of Derrick is 65 Kg.

<h2>Answer: Neptune
</h2>
The dwarf planet Pluton, <u>has the most eccentric orbit</u> (more elliptical and elongated) of all the planets, and as a consequence its orbit is "intersected" by the orbit of Neptune.
However, <u>despite this intersection, there is no collision risk between these two bodies</u>, since the orbit of Pluto is located in an orbital plane different from that of the other planets and therefore different from that of Neptune, its nearest neighbor. In addition, the orbit of Pluton is inclined 
on the the ecliptic plane (plane where the other planets move around the Sun).
