QuestionAn ant is 1/16 of an inch tall. A middle school student is 41/2 feet tall. The student goes to a learning center that is 54 feet tall. If we scale by height, then how tall would a learning center for ants be?  

 

Algebra and Up:  

Question: A man throws a computer off of a platform straight to the ground. It falls 16 feet and hits the ground in 1/2 of a second. Consider this equation for vertical distance traveled in terms of initial velocity, time, and acceleration due to gravity (32 feet/second2): 

 

(distance) = (initial velocity)(time) – 1/2(acceleration due to gravity)(time)2 

 

What is the initial velocity of the computer? 

(Hint: The computer is traveling straight down, so the distance it travels is -16 feet in this instance.)
