Answer
44 m and 7.5 m
Work Step by Step
Find the vertical displacement of the diver from equation 2.11b applied to the vertical motion. The acceleration is g, the initial vertical velocity is zero, and the time is 3.0 s.
The cliff height is 44 m.
Calculate the horizontal displacement as the horizontal velocity multiplied by the time:
(2.5 m/s)(3.0 s) = 7.5 m.
