On interstate highways in most states, mile markers indicate the distance to or from the state border, or where the highway begins or ends. On interstate 64 you travel between mile markers 41 and 107 in 1.12 hours, then turn around and return to mile marker 21 in another 1.54. what was your average speed?

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?

Can anybody me with this? ? (picture included.)
