Question

What acceleration is imparted to a football when the player kicked it with a force of 25 N? mass of football=0.40 kg

Answer 1

Force = mass x acceleration

25N = 0.40kg x acceleration
25N/0.40kg = acceleration

acceleration = 62.5 N/kg
N/kg is the equivalent of m/s²

So your acceleration is 62.5 meters per second squared
