A 4430-kg helicopter accelerates upward at 2.2 m/s2. What lift force is exerted by the air on the propellers?

  • physics -

    The propellers have to overcome the weight of the helicopter in addition to lifting it.

    Force = ma = mass * (g + 2.2) m/s²

    Can you take it from here?

    Yes! Thank you so much! I realized that you had to put gravity in but I couldn't figure out where. Thanks again!

    You're very welcome!
