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...
