After the Quiz…. A frustrated student drops a book out of a window that is 18 m above the ground. A curious student below notices that it takes 1.92 s for the book to reach the ground. (a) Draw and label a diagram of the scenario, and identify all variables. (b) Determine the acceleration of the book, rounding to one decimal place, assuming it was dropped with zero initial velocity.

Free Fall Section 3.3

“Terminal Velocity” Listen for and record the following information: 1.‘Fall Time’ 2.‘Fall Distance’

Determine: (a) The fall distance in meters. (b) The acceleration of the rider (m/s 2 )

Free-Fall -Object starts at rest (v o = 0 m/s) - In equations, “y” is used for distance (not “x”). -Object falls solely under the influence of gravity (Resistive forces of air resistance are ignored) Acceleration due to gravity: a g = m/s 2 “g” = 9.8 m/s 2
