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 9 Question 0% that the truck could not possibly accelerate at the level needed to achieve such an effect. Regardless, the police write a ticket, 0 of co Attempts Macmillan Learning and the driver's court date is approaching. 10 Question 0% The log has a mass of m = 854 kg; the truck has a mass of 0 of co Attempts M = 9.00 x 105 kg. According to the truck manufacturer, the m truck can accelerate from 0 to 55 mph in 24.0 s, but this does M 11 Question 0% not account for the additional mass of the log.
