On july 15, 2004, nasa launched the aura spacecraft to study the earth's climate and atmosphere. this satellite was injected into an orbit 705 km above the earth's surface, and we shall assume a circular orbit.
(a) how many hours does it take this satellite to make one orbit?
h
(b) how fast (in km/s) is the aura spacecraft moving?
km/s

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?
