SUMMARY
A 50 kg person standing in an elevator that accelerates upward at 1 meter per second squared exerts a force of 600 Newtons. This force is calculated using Newton's second law, F = m(g + a), where m is the mass (50 kg), g is the acceleration due to gravity (9.81 m/s²), and a is the upward acceleration (1 m/s²). The total force exerted is thus 50 kg * (9.81 m/s² + 1 m/s²) = 600 N. A free body diagram illustrates the forces acting on the person, confirming that the force exerted on the ground equals the force exerted by the ground on the person.
