etry 2/159 At the instant depicted in the figure, the radar sta- tion at O measures the range rate of the space shuttle P to be ŕ=-12,272 ft/sec, with O consid- ered fixed. If it is known that the shuttle is in a cir- cular orbit at an altitude h= 150 mi, determine the orbital speed of the shuttle from this information. Ans. v=25,474 ft/sec h = 150 mi 60° Problem 2/159

The formula v= square root 2gh gives the velocity v, in feet per second, of an object after it falls h feet accelerated by gravity g, in feet per second squared. If g is approximately 32 feet per second squared, find how far an object has fallen if its velocity is 168 feet per second.
