In my opinion, the answer is D, bc a vector is <span>a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another. Therefore giving the direction and speed. hope this helps, have a nice day :)</span>
Answer:
The escape speed of the planet is 41.29 m/s.
Explanation:
Given that,
Speed = 52.9 m/s
Final speed = 32.3 m/s
We need to calculate the launched with excess kinetic energy
Using formula of kinetic energy


We need to calculate the escape speed of the planet
Using formula of kinetic energy





Hence, The escape speed of the planet is 41.29 m/s.
