A group of students built a ramp and rolled steel balls of different sizes down the ramp onto the floor. Then they measured how far each ball rolled from the bottom ol the ramp.
Ramp Experiment Results
Mass of Steel Ball Distance Rolled
5.3 grams
1.2 meters
8.5 grams
2.0 meters
12.4 grams
3.1 meters
15.8 grams
3.9 meters
Which statement correctly explains the differences in the distances that the balls rolled?
O Friction increased as mass increased
O Velocity increased as mass increased.
Acceleration increased as mass increased.
Kinetic energy increased as mass increased.

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?
