Answer: 4550 Joules
The formula for potential energy in gravitational field is as follows:

Answer:
4750000 J
Explanation:
Kinetic Energy= 1/2* mass* velocity²
1/2*950*100²=4750000
At the highest point: kinetic energy is 0 due to the speed is 0
So the total mechanical energy is 20
Assume no frictions present, then the mechanical energy is conserved
So at the lowest point, kinetic energy = mechanical energy - potential energy
Answer will be 20 - 0.5 = 19.5 J
