Abatter hits two baseballs with the same force. one hits the ground near third base. the other is a home run out of the park. where was there more work done? explain your answer. the ball that went out of the park shows more work because the force applied was greater. the ball that hit near third base shows more work because it hit the ground much harder. the ball that went out of the park shows more work because the distance was greater. the ball that hit near third base shows more work because the force applied 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?
