If the locomotive can exert a constant pull

of 7.1 × 105 N, how long would it take to

increase the speed of the train from rest to

74.6 km/h? (Disregard friction.)

**bobpursley**, Sunday, January 9, 2011 at 5:40pmchange the speed to m/s

F=ma

F=m (change in velocity/time)

F=m * Vfinal/time

solve for time.
