If a car goes along a straight road heading east and speeds up from 45 fts to 60 ft/s in 5 s, calculate the acceleration. a = ___ Ft/s^2 [ Fill these in ]
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/h2.

For ( a= Your choices are 3 or -3. )
For ( ft/s2 your choices are W, S, N, n/a and E )
