Darryl throws a basketball at the gym floor. The ball bounces once on the floor and comes to rest in his coach's hands. At which point are all the forces on the basketball balanced?


AThe moment the ball leaves Darryl's hand
BThe moment the ball touches the floor
CWhen the ball is in the air
DWhen the ball starts falling downward before coming to rest
EThe moment the ball comes to a complete rest

Verified Answer :

Final answer:

All forces on the basketball are balanced when it comes to a complete rest, meaning the gravitational force is equal to the normal force from the ground. This occurs after the basketball has bounced and settled. Understanding the balance of forces helps explain the ball's motion and eventual stop.


Explanation:

Understanding Forces on a Basketball

In the scenario where Darryl throws a basketball, the forces acting on the ball change throughout its motion. The question of when all the forces on the basketball are balanced is crucial to understanding the dynamics involved.

When Are Forces Balanced?

  • The moment the ball leaves Darryl's hand: At this point, the ball is subject to the force of gravity pulling it downward and the force exerted by Darryl's hand, which is now gone, so forces are not balanced.
  • The moment the ball touches the floor: This is when the force of gravity is acting downward and the normal force from the floor acts upward, resulting in a balanced force if the ball was momentarily at rest before bouncing.
  • When the ball is in the air: While the ball is falling, it is under the influence of gravity, so forces are not balanced.
  • When the ball starts falling downward before coming to rest: Again, the downward gravitational force and the lack of an upward force mean they are not balanced.
  • The moment the ball comes to a complete rest: At this point, all forces are balanced because the gravitational force acting down is equal to the normal force acting up, leading to a net force of zero.

Therefore, the correct answer to the question is the moment the ball comes to a complete rest. At this point, there is no net force acting on the basketball, indicating that all forces are balanced.
