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 24° with respect to the vertical while the aircraft accelerates for takeoff, which takes about 17 seconds. Estimate the takeoff speed of the aircraft.
Meghan, Maddy, Hannah, Cameron -- please do not switch screen names. We know that only one person posted the last 8 physics questions.
You'd have more luck getting help by sticking with one name and showing us what you do and don't know about each problem. Otherwise, it just looks like homework dumping and mooching.
