When a soccer ball with a mass of 0.43kg is kicked by a player, the ball can accelerate 25 m/s² off the player's foot. If resisting forces are ignored, such as friction and air resistance, how many Newtons of force did the player use when kicking the ball?
To calculate the force used by the player when kicking the ball, we can use Newton's second law of motion, which states that force equals mass times acceleration.
Given:
Mass (m) = 0.43 kg
Acceleration (a) = 25 m/s²
Using the formula:
Force (F) = mass (m) × acceleration (a)
F = 0.43 kg × 25 m/s²
F = 10.75 N
Therefore, the player used 10.75 Newtons of force when kicking the ball.
