    How Do You Calculate Force on a Passenger in an Accelerating Elevator?

    Ah. I got it. The problem was the cm - m conversion. Thanks for the help though. My teacher's a psychopath.

    How Do You Calculate Force on a Passenger in an Accelerating Elevator?

    so: Fa - mg = ma Fa = ma + mg Fa = (100)(3) + (100)(-9.8) Fa = 680 That doesn't seem right.

    How Do You Calculate Force on a Passenger in an Accelerating Elevator?

    Okay, so mg = 100(-9.8) = -980. I'm not sure about the force of acceleration. Is is 30?

    How Do You Calculate Force on a Passenger in an Accelerating Elevator?

    No, I'm sorry, it doesn't. The only formula I've learned so far is "force equals mass times acceleration" Can you show me how you got the other formula?

    How Do You Calculate Force on a Passenger in an Accelerating Elevator?

    The person should have an acceleration of 30 too, since he's inside the elevator. This gives me: Sum of Forces = mass x acceleration Sum of Forces = 100 (30) Sum of Forces = 3000 When you subtract the force from gravity (-980) the normal force acting on the guy from the elevator is 3980 N...

    How Do You Calculate Force on a Passenger in an Accelerating Elevator?

    I need a little help with this problem. I know what the answer is, but not how to get it. --- A passenger in an elevator has a mass of 100 kg. Calculate the force in Newtons exerted on the passenger by the elevator if the elevator is moving upward with an acceleration of 30 cm/s^2. ---...
