For the unit to be consistent, convert 38 ft/s^2 to mi/h^2. Use the conversion factor,

1 mile = 5280 feet and 1 hour = 3600 seconds.

So,

`38 `  `(ft)/s^2`  `xx`  `(1 mi)/(5280ft)`  `xx` `( 3600s)^2/(1h)^2` `=` `93272.27` `(mi)/h^2`

Then, use the formula of constant acceleration to determine the distance travelled (s) by the car before it came to stop. The...
