Basically, the "push back" of the air against the object moving forward. It acts similar to friction, except the resistance is based on the shape of the object instead of the interaction of the object and the ground
The formula for potential energy would be PE = mgh
Where: m is the mass; g is the acceleration due to gravity, and h would be height.
So plugging in the data:
PE = 150kg × 9.8 m/s^2 × 10m
= 14700 Joules would be the potential energy for this problem.

(h + .16) m g = 1/2 k x^2 total PE of block relative to where it stops
(h + .16) .82 * 9.8 = .5 * 120 * .16^2 PE released = PE of spring
8.04 h + 1.29 = 1.536
h = (1.536 - 1.29) / 8.04 = .031 m = 3.1 cm
Answer:
640.5
Explanation: i got it right on acellus
Energy cannot be created or destroyed
I hope that helps
