Suppose that a passenger intent on lunch during his first ride in a hot-air balloon accidently drops an apple over the side during 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.a.)What is the magnitude of the acceleration of the apple just after it is released?b.What is the direction of the acceleration of the apple just after it is released?c.Just then, is the apple moving upward or downward, or is it stationary?d.What is the magnitude of its velocity just then?e.In the next few moments, does the speed of the apple increase, decrease, or remain constant?

Suppose that a passenger intent on lunch during his first ride in a hot-air balloon accidently drops an apple over the side during 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.

a.)What is the magnitude of the acceleration of the apple just after it is released?

b.What is the direction of the acceleration of the apple just after it is released?

c.Just then, is the apple moving upward or downward, or is it stationary?

d.What is the magnitude of its velocity just then?

e.In the next few moments, does the speed of the apple increase, decrease, or remain constant?

Expert Answer

Step 1

a) The apple gets dropped during the lift off. It is under the influence of gravity. Therefore, the acceleration of the apple a is equal to the acceleration due to gravity g. Hence, a = 9.8 m/s2.

Step 2

b) The acceleration of apple is downwards as gravity pulls it towards the earth.

Step 3

c) Consider earth as a frame of reference. In this reference frame, it is as if the ball has an upward acc...
