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.

  • Math - ,

    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)
