Question

A person weighs a fish of mass m on a spring scale attached to the ceiling of an elevator as illustrated is shown.
(A) Show that if the elevator accelerates either upward or downward, the spring scale gives a reading that is different from the weight of the fish.
(B) Evaluate the scale readings for a 40.0-N fish if the elevator moves with an acceleration a_y = ±2.00 m/s².

When the elevator accelerates
When the elevator accelerates
upward, the spring scale reads
a value greater than the
weight of the fish.
downward, the spring scale
reads a value less than the
weight of the fish.
