A football quarterback throws a football. After it leaves his hand, what forces are acting on the football? Choose all that apply: The drag force from the air The normal force from the ground A thrust force The weight force from the Earth The force from the quarterback's hand

Respuesta :

Answer:

The force of weight and drag force of the air

Explanation:

This is because when the ball leaves the hand the only force acting on it is the gravity of the earth, therefore its weight, since the force applied by the quarterback is no longer being applied to the ball. You can also consider the drag force of the air in the ball but in some cases it is minimal and can be neglected.

The forces acting on the ball as it leaves the hand of the quarterback are;

  • the drag force from the air, and
  • the weight force from the Earth.

The upward motion of an object thrown upwards is reduced by the opposing force. These opposing forces act in opposite direction to the motion of the object.

When the football is thrown upward, the force from the quarterback provides the thrust force with the ball moves upwards, after the ball leaves the hand of the quarterback the upward motion is reduced by opposing forces.

These opposing forces include the following;

  • the drag force from the air
  • the weight of the ball due to gravitational force of Earth

Thus, form the given options, the forces acting on the ball as it leaves the hand of the quarterback are the drag force from the air and the weight force from the Earth.
