An SUV with a mass of 1,882 kg is traveling eastbound at 14m/s, while a compact car with a mass of 1,015 kg is traveling westbound at 15 m/s. The cars collide head-on, becoming entangled. What is the velocity of the entangled cars? [Please round to two decimal places.]

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

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?
