SUMMARY
A basketball dropped from a height of 2 meters loses 20% of its energy upon bouncing due to air friction. The initial potential energy (PE) is calculated using the formula PE = mgh, where g is 9.8 m/s². After losing 20% of its energy, the remaining energy can be expressed as 80% of the initial potential energy, leading to the equation mgh1 = 0.80(mgh) + mgh2. This allows for the calculation of the height of the first bounce (h2).
