2013 F = ma Exam — Question 9

The following information applies to questions 8 and 9 A truck is initially moving at velocity v. The driver presses the brake in order to slow the truck to a stop. The brake applies a constant force F to the truck. The truck rolls a distance x before coming to a stop, and the time it takes to stop is t. 9. Which of the following expressions is equal the initial momentum of the truck (i.e. the momentum before the driver starts braking)?
