An egg is dropped from a height of 90 ft. If acceleration due to gravity is –16 ft/s2 and initial velocity is 0 ft/s, approximately how long will it take for the egg to reach the ground?h(t) = at2 + vt + h0

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) ≈ 2.4 seconds. The egg reaches the ground in approximately 2.4 s, choice B.
