Question
Paulina kicks a football.
It accelerates towards the goal at 10 m/s².
The ball has a mass of 430 g.
With what force did Paulina kick the ball?
Solution
To find the force with which Paulina kicked the ball, we can use Newton's second law of motion, which states that Force = mass * acceleration.
-
First, we need to convert the mass of the ball from grams to kilograms, because the standard unit of mass in physics is kilograms. There are 1000 grams in a kilogram, so 430 grams is 0.43 kilograms.
-
Next, we multiply the mass of the ball by its acceleration. The acceleration is given as 10 m/s². So, Force = 0.43 kg * 10 m/s² = 4.3 Newtons.
Therefore, Paulina kicked the ball with a force of 4.3 Newtons.
