You see a drone heading straight towards your position flying at a height of 13.0 m above you. The speed of the drone is 21.6 m/s. You have an object that you plan on throwing straight up into the air so that the drone will fly into it as it passes directly over your head. Your plan is to throw the object straight up with an initial velocity such that it will just stop moving up at the same instant the drone will fly into it. How many seconds before the drone is directly overhead should you throw the object up into the path of the drone?
