Answer:
At which point does the planet have the least gravitational force acting on it?
Explanation:
In an elliptical orbit, when a planet is at its furthest point from the Sun, it is under the least amount of gravity, meaning that the force of gravity is strongest when it is closest.
Answer:
D. 2 m/s²
Step-by-step explanation:
Initial speed of the runner (u) = 6 m/s
Final speed of the runner (v) = 14 m/s
Time taken (t) = 4 s
By using equation of motion, we get:

Acceleration of the runner (a) = 2 m/s²
