I am trying to help a friend with this webassign 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 . She notices that the string makes an angle of 23° with respect to the vertical while the aircraft accelerates for takeoff, which takes about 18 seconds. Estimate the takeoff speed of the aircraft.
I just need a kick in the rear to get me started! I know that there is Tension and weight acting on the watch. I know that average a=v/t so average v=at and I know that F=ma
But I am having trouble putting it all together since I do not have any mass or other numbers besides 18s.
Anyone got a hint for me?
Thanks,
Casey
