Final answer:
To draw a free-body diagram for a football moving upwards towards its peak, we consider the forces of gravity and air resistance. Gravity is directed downwards, while air resistance is directed upwards.
Step-by-step explanation:
To draw a free-body diagram, we need to consider the forces acting on the football as it moves upwards towards its peak. The main force acting on the football is gravity, which is directed downwards. We represent this force with an arrow pointing downwards. Since the football is also moving upwards, there is a force opposing gravity called air resistance. We represent this force with an arrow pointing upwards. These two forces represent the main free-body diagram of the football when it is moving upwards towards its peak.
