Assume there is a class AirConditioner that supports the following behaviors: turning the air conditioner on and off, and checking if the air conditioner is on or off. The following methods provide this behavior: turnOn and turnOff, setTemp, and isOn, which accepts no argument and returns a boolean indicating whether the air conditioner is on or off. Assume there is a reference variable myAC to an object of this class, which has already been created. There is also a boolean variable status, which has already been declared. Use the reference variable, to invoke a method to find out whether the air conditioner is on and store the result in status.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
