 $a = 0.03125 \, \text{ ft/sec}^2$
 

 $625 = \frac{1}{2}(0.03125)t^2$

 $t = 200 \, \text{ sec}$

 $t = 3 \, \text{ min } 20 \, \text{ sec}$       answer

 $a = 0.009\,525 \, \text{ m/sec}^2$
 

 $190.5 = \frac{1}{2}(0.009\,525)t^2$

 $t = 200 \, \text{ sec}$

 $t = 3 \, \text{ min } 20 \, \text{ sec}$       answer
