Presume that a passenger intent on lunch through his first ride in a hot-air balloon accidently drops an apple over the side through the balloon’s liftoff. At the moment of the apple’s release, the balloon is accelerating upward with a magnitude of 4.0 m/s2 and has an upward velocity of magnitude 2 m/s.
What is the magnitude of the acceleration of the apple just after it is released in m/s^2?
Just then, is the apple moving upward or downward, or is it stationary?
In the next few moments, does the speed of the apple increase, decrease, or remain constant?
