Answer:
1. PE = 20000J
2. KE = 25000J
3. KE = 32500J
4. KE = 35000J
Explanation:
This question is based on Law of conservation of Energy which states that total energy always remain same, it just changes from one form to another.
According to this law, with reference to the question, total energy is PE + KE = 40000J, which will be same throughout the rolar coaster's ride. Therefore at any given moment PE and KE should sum upto 40000J. You can then use this information to find the value of PE and KE and any given instant.
