SUMMARY
In the discussion, the calculation of how far Dave Johnson's center of mass moves upward during his high jump is addressed. Given his vertical velocity component of 6 m/s, the conversion of kinetic energy into potential energy is the key principle for solving this problem. Using the formula for gravitational potential energy, the height can be determined by equating kinetic energy (1/2 mv²) to potential energy (mgh). This results in a maximum height of 1.83 meters for his center of mass.
