1. The problem statement, all variables and given/known data Suppose you have a cantaloupe (C) on a table (T). Let FTC be the force on the table by the cantaloupe, and let FCT be the force on the cantaloupe by the table. Do the magnitudes of these forces increase, decrease, or stay the same if they are placed in an elevator which begins to accelerate upwards? 2. Relevant equations 3. The attempt at a solution I take the upward direction as positive. Please see the attached photo (my attempt). My solution shows that the magnitude of FCT increases, while the magnitude of FTC decreases. The solution, however, claims they both increase. Where have I gone astray?
