2. A book is thrown off the ceiling of NDHS with no initial downwards velocity. The building is 20 meters tall, and it falls at the acceleration of gravity a 9.8 m/s. Assume it has an initial x-velocity of 5 m/s. What is the book's displacement in x? Hint: solve for time using the book's y-movement first. 9 1₁2 = - a 2 m
