Projectiles: A monkey is sitting at the top of a tree 20 m above ground level. A person standing on the ground wants to feed the monkey. He uses a bow and arrow to launch the food to the monkey. If the person knows that the monkey is going to drop from the tree at the same instant that the person launches the food, how should the person aim the arrow containing the food? Air resistance is small enough to be ignored.
A) He should aim it at the monkey.
B) He should aim it below the monkey.
C) He should aim it above the monkey.

The person should aim directly at the monkey because, in the absence of air resistance, both the food and the monkey will fall towards the ground with the same acceleration due to gravity. This means they will remain in line with each other during their descent.
