14. You are in the enclosed cargo area of a truck, unable to see outside. The truck is initially at rest. A small mass hangs from the ceiling with a piece of string. At first, the mass hangs straight down. The mass swings towards the front of the truck for five seconds, then returns to a vertical position. Ten seconds later, the mass swings to the left side of the truck for a few seconds, then returns to a vertical position. What sort of motion did the truck engage in? A. The truck accelerated forward for 15 seconds and then turned. B. The truck accelerated backward for 5 seconds, then stopped moving for ten seconds, then started again and turned. C. The truck accelerated forward for 5 seconds, then continued moving forward at a constant velocity for 10 seconds, then turned. D. The truck accelerated backward for 5 seconds, then continued moving backward at a constant velocity for 10 seconds, then turned. E. The truck accelerated backward for 15 seconds, then turned.
