Three-particle system, with masses m1 = 3.0 kg, m2 = 4.0 kg, and m3 = 8.0 kg. What are (a) the x coordinate and (b) the y coordinate of the system’s center of mass? (c) If m3 is gradually increased, does the center of mass of the system shift toward or away from that particle, or does it remain stationary?

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?
