A pickup truck has a wheelbase of 3.00 m. Ordinarily, 10,780N rests on the front wheels and 8820 N on the rear wheels when the truck is parked on a level road. a. A box weighing 3600N is now placed on the tailgate, 1.00 m behind the rear axle. How much total weight now rests on the front wheels?
b. On the rear wheels? (b) How much weight would need to be placed on the tailgate to make the front wheels come off the ground?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to. in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
