At the bottom of the motion: The potential energy of the spring is at a maximum since the spring is stretched at its maximum extension. The potential energy due to gravity is at a minimum, since the mass is lifted the least amount above ground.
- Y divided by Z = 8 divided by 4 = 2
- 8x = 8 x 12 = 96
- 2 + 96 = 98
ANSWER: 98
