 Homework Statement
 Calculate your acceleration while jumping, the net force that acts on you while jumping, and the force you exert on Earth when you jump.
 Homework Equations

w = mg
acceleration = Net force / mass
2.2 lb = 1 kg
This question required measurements which are the following:
my weight = 108 lbs
crouching distance (the distance from my regular height to where I crouch) = 90.6 cm
jump height = 60.4 cm
I first converted lb to kg, and I got 49.09 kg. I then used this value for w = mg and inputted 9.80 for g and got w = 481.09 N. I then used this force for a = net force / mass and found the acceleration to be 9.7999 m/s/s.
This answer was wrong, and I was wondering why I went wrong in my work. The answer made sense to me — the only force, neglecting air resistance, acting on someone in the middle of their jump is acceleration due to gravity.
