A person dangles her watch from a string while the plane takes off. She notices that the string makes a angle of 25 degrees with respect to the vertical whie the plane accelerates to take off, which takes 19 seconds. What is the takeoff speed of the plane?
How do I get started? I think the X component is (Tension of String)*cos(25) and the Y component is (Tension of String)*sin(25)?
How do I find the accerleration without knowing the mass of the watch?
