Can someone please help me with this problem?? : (
Jean, who likes physics experiments, dangles her watch from a thin piece of string while the jetliner she is in takes off from Dulles Airport (Fig. 4-55). She notices that the string makes an angle of [COLOR=#000000]24[/COLOR]° with respect to the vertical while the aircraft accelerates for takeoff, which takes about [COLOR=#000000]18[/COLOR] seconds. Estimate the takeoff speed of the aircraft.
