Dave and sandy hartranft are frequent flyers with a particular airline. they often fly from city a to city b, a distance of 732732 miles. on one particular trip, they fly into the wind, and the flight takes 22 hours. the return trip, with the wind behind them, only takes 1 and one half1 1 2 hours. if the wind speed is the same on each trip, find the speed of the wind and find the speed of the plane in still air

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
