Two descriptions about physical quantities are given below: Quantity A: It has the same unit as force. Quantity B: It measures the amount of matter in an object. What quantities are these most likely describing? (4 points) Both Quantity A and Quantity B are mass. Both Quantity A and Quantity B are forces. Quantity A is weight and Quantity B is mass. Quantity A is mass and Quantity B is weight.

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?
