A particle of mass m=5 kg is initially moving in the +x direction with a constant velocity v0=500 m/s. At time t=0, at a position x=0, the particle is suddenly pushed in the -x direction by a constant force of F=-100 N. How far does the particle travel before changing directions? In order words, how far does the particle travel before its instantaneous velocity is 0?

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?
