A 1.50 x 10^3 kg car traveling at 100 km/h South collides with a 1.20 x 10^3
kg car traveling North at 100 km/h. The heavier
car continues to move South after the collision,
but slows to 25.0 km/h. How fast is the lighter car
moving after the collision?

Which best represents the law of conservation of mass ?

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?

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?
