One of the world's fastest roller coasters is located in a theme park in Valencia, California. Riders go from 0 to 100 miles per hour in 7 seconds. Find the acceleration of the roller coaster during this time interval in miles per second squared.

acceleration = change in velocity/change in time
= 100 miles per hour/7 second
= (100 miles per 3600 seconds)/7 seconds
= 100 miles/25200 sec^2
= .004 miles/sec^2 (correct to 3 decimals)
