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.
This is a trick question, isn't it? If a car is stuck in traffic, it doesn't matter how fast it can travel, because it isn't moving at all. Therefore the average speed would be zero, right?
V^2 = 2a S
V = square root ( 2 x 0.5 . 4)
V = 2 m/s
Answer is B
