Arigid rod is rotating at a constant angular speed about an axis that is perpendicular to one end of the rod. a small ball is fixed to the rod at a distance that is 12 cm from the axis. the centripetal force acting on this ball is 1.7 n. what would be the centripetal force that acts on the ball if the ball were fixed to the rod at a distance of 33 cm from the axis?

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?
