Final answer:
To kick a 16 kg ball at a rate of 4 m/s, the player would need to exert a force of 25.6 Newtons.
Step-by-step explanation:
To calculate the force required to kick a 16 kg ball at a rate of 4 m/s, we can use the equation F = m * a, where F is the force, m is the mass, and a is the acceleration.
In this case, the acceleration can be calculated using the equation a = v / t, where v is the velocity and t is the time. Substituting in the given values, we get a = 4 m/s / 2.5 s = 1.6 m/s².
Now we can calculate the force: F = 16 kg * 1.6 m/s² = 25.6 N.
