If a car goes along a straight road heading east and speeds up from 45 ft/sec to 60. ft/sec in 5 sec, calculate the acceleration.
= 33 ft/sec 2 NESn/aW
Note: If the speed were given in miles per hour, and the time were given in minutes, you could change the minutes to a fraction of an hour and do the problem. The answer would be in miles/hr2.
