1. The problem statement, all variables and given/known data
Ok, relatively simple question here, but I have a newb doubt....

"A basketball player with a mass of 112kg can jump 0.92 m into the air during a slam dunk competition. Calculate the force that pulls the player back towards the floor."

2. Relevant equations
$\vec f = m \vec g$

3. The attempt at a solution
Is the 0.92 m height a red herring distraction?

If so it's just a straightforward 112 kg x 9.8 m/s^2 = 1098 N answer.

Am I correct to ignore the 0.92 m height?

Apologies in advance for such a basic question.

It is absolutely a red herring. The force of gravity on the player close to the surface of the earth is always his mass multiplied by $g$.
