Can you help me with this problem

A person weighs a fish of mass m on a spring scale attached to the ceiling of an elevator as illustrated in the figure When the elevator accelerates When the elevator accelerates upward, the spring scale readsdownward, the spring scale a value greater than the weight of the fish. reads a value less than the weight of the fish (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 41.0-N fish if the elevator moves with an acceleration ay = ±2.36 m/s* 6 4 SOLVE IT (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 mg mg A fish is weighed on a spring scale in an accelerating elevator car

Explanation / Answer

Here , for part

B)

1) first T reading is

T = 41 * (2.36/9.8 + 1) = 50.9 N

for the second T

T = 41 * (-2.36/9.8 + 1) = 31.1 N

---------------------------------------

Now, for the final ,

let the acceleration is a

net force acting on her

4.7 * m * g - m * g = m * a

a = 3.7 * g

a = 3.7 * 9.8

a = 36.3 m/s^2

the acceleration of the rocket is 36.3 m/s^2
