Question

Consider applying Newton’s second law to a man riding an elevator (perhaps to calculate his acceleration).

Which of the following forces must be considered? Choose all that apply. The force that the man's head exerts on his neck The force that the man's feet exert on the floor of the elevator The force of gravity on the man The force that the elevator floor exerts on the man's feet The force the elevator cable exerts on the elevator car The force of gravity on the elevator I give up!

Answer 1

- of elevator cable exests on cil The force crevator car. (in The force of gravity on the elevaton. Explanation : As man is inside elevator so man's acceleration is equal to elevator's acceleration, So we need to consides forces acting on elevator. o T = (force of elevator cable) Y Fg = (force of gravity on elevator ) so, net force = 17- Fgl also net force ama la= Toto m » since mass of mass so we person can is negligble than elevator neglect man's mans. -
