Gce Model Questions Vol1 2021 Mathematics Question 15
Practice objective / multiple choice question 15 from the 2021 Gce Model Questions Vol1 Mathematics examination.
The time \(t\) (in seconds) for a stone to fall from rest is directly proportional to the square root of the height \(h\) (in metres): \(t = k\sqrt{h}\). A stone dropped from a height of 20 m takes 2.0 s. Because of air resistance, the actual time for a drop from 45 m is 1.5 s longer than the time predicted by the direct‑variation law. Find the measured time (in seconds) for the 45 m drop, correct to two decimal places.
