Suppose the space shuttle is in orbit 300 km from the earth's surface, and circles the earth about once every 90
minutes. find the centripetal acceleration of the space shuttle in its orbit. express your answer in terms of g, the
gravitational acceleration at the earth's surface. (hint: the earth's radius is 6.4 x 10 m.]

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
