While hauling a log in the back of a flatbed truck, a driver is
pulled over by the state police. Although the log cannot roll
sideways, the police claim that the log could have slid out the
back of the truck when accelerating from rest. The driver claims
that the truck could not possibly accelerate at the level needed to
achieve such an effect. Regardless, the police write a ticket, and
the driver's court date is approaching. The log has a mass of m =
954 kg; the truck has a mass of M = 9.10 x103 kg. According to the
truck manufacturer, the truck can accelerate from 0 to 55 mph in
22.0 s, but this does not account for the additional mass of the
log. Calculate the minimum coefficient of static friction us needed
to keep the log in the back of the truck.
