Arocket blasts off. in 10.0 seconds it is at 10,000 ft, traveling at 3600 mph. assuming the direction is up, calculate the acceleration. (hint: the rocket is not under constant acceleration). 5280 ft/s2 528 ft/s2 100 ft/s2 200. ft/s2

       Acceleration  =  (change in speed)  /  (time for the change)

Change in speed = (ending speed) - (beginning speed)

                            =     (3,600 mi/hr) - ( 0 )

                            =       3,600 mi/hr

                            =     same as  1 mile/second.

Acceleration  =  (1 mi/sec) / (10 sec)

                      =     0.1 mi/sec² .

But 1 mile = 5,280 ft,
so
                       0.1 mi/s²  =  528 ft/s²          

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. the winds blow from west to east in jet streams but the flow often shifts to the north and south. jet streams follow the boundaries between hot and cold air. the earth's rotation is responsible for the jet stream as well.
