A 90-kg man stands in an elevator that has a downward acceleration of 1.4 m/s².The force exerted by him on the floor is about: A)0 N B)90 N C)760 N D)880 N E)1010 N

Question

Quizplus · Accepted Answer

The force exerted by the man on the floor of the elevator can be calculated using the formula F = m(g - a), where m is the mass (90 kg), g is the acceleration due to gravity (9.8 m/s^2), and a is the acceleration of the elevator (1.4 m/s^2). Thus, F = 90(9.8 - 1.4) = 90(8.4) = 756 N, which is approximately 760 N.
