Study this model of a gravitational slingshot. Then answer the questions. In this model, the velocity of the spacecraft at position 2 is the velocity of the craft at position 4. At position 1, the direction of the spacecraft changes because of . Position 3 represents the .

Explain in physical terms how a microwave oven works. what would happen when you put a conductor in the microwave oven? explain.

Asuppose a suitcase has a mass of (m) 30 kg and a net force (n) of 10 kg*m/s. what is the acceleration rate of the suitcasein m/s? show your work to support your answer.

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?
