Question 20 • Algebra II
Use the height equation with acceleration −16 ft/s², initial velocity 0 ft/s, and starting height 90 ft: h(t) = −16t² + 90. At the ground, h(t) = 0, so 16t² = 90 and t = √(90/16) ≈ 2.37 seconds. The egg takes approximately 2.4 seconds to reach the ground, which is choice C.
