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.

leva [86]

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,

$F = ma$

Where,

$F$ - force

$m$ - mass = 0. 25 kg

$a$ - acceleration = 5 N

Put the values in the formula,

$F = 0.25 \times 5\\\\F = 1.25 \rm \ N$

Therefore, the force exerted on Alice’s foot as she kicks the ball is 1.25 N.

If there were a galaxy moving closer to earth then that would contradict the Big Bang theory since the entities should be moving away from earth and from each other.
