Question

Net force acting on a 100 kg man standing in an elevator accelerating downward with a = 9. 8m/s^2 comes out to be:(a) 980N(b) 580N(c) 1380N(d) zero

Answer 1

(d) zero

Step-by-step explanation:

Net acceleration = (a - g)

a is downward so it is positive

F(net) = ma(net)

F = 100 x (9.8 - 9.8)

F = 0

The correct option is (d).
