A large fish hangs from a spring balance supported from the roof of an elevator.

If the elevator has an upward acceleration of 2.65 m/s^2 and the balance reads 70.0 N, what is the true weight of the fish?

Under what circumstances will the balance read 34.0 N? (what acceleration)

What will the balance read if the elevator cable breaks?


I will be happy to review your thinking or work on this.


If only I did know what to do...


Force= mass(totalacceleration)
= mass(acceleration upward + g)
