A planet orbits a star in an elliptical orbit. At a particular instant the momentum of the planet is <-3.9 x 10^29, -1.6 x 10^29, 0> kg*m/s, and the force on the planet by the star is <-3.3 x 10^22, -1.9 x 10^23, 0> N. Find FlI and FI_ (Express your answers in vector form.)

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?
