The rear side of a truck is open and a box of mass 2 kg is placed on the truck 8 meters away from the open end. μ = 0.1 and g = 10m/s^2. The truck starts from rest with an acceleration of 2m/s^2 on a straight road. The box will fall off the truck when it is at distance from the starting point equal to
