Miss Atkins is on her first space walk. Her mass is 80.0 KG and she carries an empty oxygen tank with a mass of 10.0 KG. She throws the tank away from her self with the speed of 2.0 m/s. With what speed does she start to move off into space? Both the astronaut and the Tanger motionless before she throws the tank.

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?
