The time taken for the APUSH textbook to hit the ground is determined as 0.55 seconds.
The time of motion of an object is the time taken for the object to travel from its initial point to the final point.
The time taken for the APUSH textbook to hit the ground is calculated as follows;
t = √(2h/g)
where;
h is the height of fall of the textbook
g is acceleration due to gravity
t = √(2 x 1.5/9.8)
t = 0.55 seconds
Thus, the time taken for the APUSH textbook to hit the ground is determined as 0.55 seconds.
