Question

A 750-newton person stands in an elevator that is
accelerating downward. The upward force of the
elevator floor on the person must be
(1) equal to 0 N (3) equal to 750 N
(2) less than 750 N (4) greater than 750 N

1 Answer

  • When an elevator is accelerating downward, the normal force is equal to mg-ma (hence you feel a little lighter when accelerating downwards)

    Therefore, the upward force of the elevator floor on the person must beĀ less than 750N
