A 900 Kg truck is driving at 45 m/s when it hits a large soft object and becomes embedded with it.
A: Find the amount of work the object does to bring the truck to a stop.
B: The truck comes to a stop in 5.4 m. Find the force applied to the truck by the object and how much time it took to stop the truck.
