The log has a mass m= 984 kg; the truck has a mass M=8750 kg. According to the truck manufacture, the truck can accelerate from 0-55 mph in 23.0 seconds, but this doesnt accont for the additional mass of the log. Calculate the minimum coefficent of static friction u needed to keep the log in the back of the truck.
