The log has a mass of m = 919 kg; the truck has a mass of M = 8550 kg. According to the truck manufacturer, the truck can accelerate from 0 to 55 mph in 28.0 seconds, but this does not account for the additional mass of the log. Calculate the minimum coefficient of static friction ?s needed to keep the log in the back of the truck.
