# What is the normal force when a 40 kg person jumps and is accelerating at 3 m/s2 upward while in contact with the ground?
## F is up, +
F - m g = m a
F = m(g+a) = 40 (9.81+3)
## To find the normal force acting on a person while jumping, we need to consider the forces acting on the person in equilibrium.
