A 12.0-kg box rests on the flat floor of a truck. The coefficients of friction between the box and floor are : static = 0.19 and kinetic =0.15. The truck stops at a stop sign and then starts to move with an acceleration of 2.20 m/s^2.

1. If the box is 1.80 m from the rear of the truck when the truck starts, how much time elapses before the box falls off the truck?

2. How far does the truck travel in this time?
