The same force is applied to two skateboards. One rolls across the room and the other moves a few feet and comes to a stop. Where was there more work done? (2 points) Select one:
a. The skateboard that traveled the shorter distance shows more work because there was more resistance.
b. The skateboard that traveled the longer distance shows more work because it was lighter.
c. The skateboard that traveled further shows more work because the distance was greater.
d. The skateboard that traveled the shorter distance shows more work because the force was greater.

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?
