Seat belts are required in all small buses, but in many states large busses are not required to have seat belts. Construct an arguement for seat belts busses. 1. Explain what happens in an accident (include inertia, force, mass, and acceleration)
2. Be sure to explain how seat belts work. (Include force, mass and acceleration)
Explain how a child's body will move with and without a seatbelt(include force, mass and acceleration)

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?

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

On a geologic map, if the contacts between sedimentary rock units form a bull’s-eye pattern of concentric circles, with the youngest unit in the center, the underlying structure is a(n)
