1. The problem statement, all variables and given/known data A cup of coffee is dropped aboard an airplane accelerating along a smooth runway. If it falls a vertical distance of 1.0 meter, find its horizontal displacement when it hits the floor. Assume a constant horizontal acceleration of 1.5m/s^2 for the airplane. 2. Relevant equations F=ma 3. The attempt at a solution This chapter is about noninertial reference systems, if that means anything for this problem. I looked at the problem and said there was a force due to gravity and a force from the horizontal acceleration. f=ma=mg+ma1 v(dv/dx)=g+a1 I dont think I started this correctly, because we don't have a velocity. Am I going in the right direction here?
