Giving 40 points Suppose you must design an experiment to test how a paper airplane's shape affects the distance it will fly. Your plane must fly halfway across your classroom to get the best grade. The teacher reminds you to use both imagination and logical reasoning in your design.

Write a procedure for an experiment that tests how a paper airplane's shape affects the distance it will fly. Then, describe how you might use both imagination and logical reasoning to increase your chances of discovering an airplane shape that will fly at least halfway across the
classroom.

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?
