Chewbacca and Han Solo have got to get a safe full of Imperial Credits to an elevator 10.0 m away. Chewbacca can push with a force of 425 N and Han Solo can pull with a force of 355 N. If the coefficient of kinetic friction between the safe and the floor is 0.250, how long will it take for them to get the elevator to the safe, if starting from rest and if the safe has a mass of 300 kg.
