A 5.0kg salmon is weighed by hanging it from a fish scale attached to the ceiling of an elevator. What is the apparent weight of the salmon if the elevator is (a) at rest, (b) moving upward at 2.5 m/s2, and (c) moving downward at 3.2 m/s2?

2. Relevant equations

Sum of F = 0

F(t) - W = 0

F(t) = W

Sum of F = Ma

F(t) - W = Ma (W=mg)

F(t)<W Sum of F = Ma

W- F(t) = Ma

3. The attempt at a solution

i have trouble thinking out of the box to get the problem started. this is my very first time ever taking physics and i have not had a math or science class in a year. can anyone help me get started?! I would appreciate any help! Thank you!
