Question summary: Solve the problem. When a person bends at the waist with a straight back, the force, F, exerted by the person's lower back muscles can be estimated with the formula where w is the person's weight, and θ is the angle made by the person's torso relative to the horizontal. Suppose that a person bends at an angle of 30°. Determine the force exerted by the person's back muscles, and estimate the angle that requires the back muscles to exert a force of 346 pounds.: 501 pounds; 53.2°; 26 pounds; 53.2°; 501 pounds; 30°; 289 pounds; 47.3°
Right answer summary: 501 pounds; 53.2°
