In her gymnastic routine, Regina dismounts from the uneven-parallel bars and lands straight-legged on the ground, compressing her 0.250 m long femur by 2.10×10^(-5) m. If the femur has a cross-sectional area of 3.00×10^(-4) m^2 and the stress modulus of bone is 2.00×10^10 N/m^2, with how much force does Regina hit the ground?
