A 6520 kg helicopter accelerates upward at 0.57 m/s2 while lifting a 1190 kg car. (a) What is the lift force exerted by the air on the rotors? _________ N (b) What is the tension in the cable (ignore its mass) that connects the car to the helicopter? _____N I have no idea how to do this and it is going to be on my mid-term. Can someone please help me because I keep getting very strange numbers. I used a kinetics equation but the answer was wrong!
