A helicopter with a mass of 1.5 X 10^3 kg rises with a vertical acceleration of 12 m/s 2 . The crew and the passengers have a total mass of 4.2 X10 ^2 kg. Express the magnitude and direction of the force on the floor by the crew and the passengers. I am very confused on how to approach this problem. Can someone help me understand?
