Alice kicks a 0. 25 kg soccer ball with 0. 5 N of force. What force does the ball exert on Alice’s foot as she kicks it? N.
1 answer:
The force exerted on Alice’s foot as she kicks the ball is 1.25 N.Force can be defined as the influence that can accelerate the object.
<h3>What is force?</h3>
Force can be defined as the influence that can accelerate the object. From Newton's Second Law of motion,
Where,
- force
- mass = 0. 25 kg
- acceleration = 5 N
Put the values in the formula,
Therefore, the force exerted on Alice’s foot as she kicks the ball is 1.25 N.

Answer:
Reflective
Explanation:
The radiation pressure of the wave that totally absorbed is given by;
and While the radiation pressure of the wave totally reflected is given by;
Now compare the two-equation you can clearly see that the pressure due to reflection is larger than absorption therefore the sail should be reflective.
