SUMMARY
The discussion focuses on calculating the energy dissipated by air drag on a .63 kg ball thrown upwards at an initial speed of 14 m/s, reaching a maximum height of 8.1 m. The kinetic energy (KE) is calculated using the formula KE = 1/2 MV², resulting in 61.74 J. The energy dissipated due to air drag is determined to be -12 J, which is found by comparing the change in kinetic energy with the change in potential energy (mgh). This highlights the impact of air resistance on the ball's ascent.
