1. The problem statement, all variables and given/known data Audrey McLaughlin has a vehicle with a built-in rectangular swimming pool. The pool is 2.4m long, 1.4m wide, and is partly filled with water to a constant depth of 1.2m as shown. Calculate the minimum additional height, h, to avoid water spillage when the vehicle maintains a steady forward acceleration of 4.9m/s^2 on a horizontal road. Ignore and "sloshing" motion associated with changes in acceleration. Answer in cm. Data: dimensions of tank are 2.4m long and 1.4m wide, and the water is filled to a height of 1.2m The question is asking about the additional height that the tank must have to not have any water spillage. Options: A) 120cm B) 107cm C) 84cm D) 60cm E) 54cm 2. Relevant equations Net force? Maybe conservation of energy equations? 3. The attempt at a solution The only way I can think of to solve this question is to find the angle of the net force acting on the water. I did this using components method, adding mg + (m x acceleration of truck (4.9m/s^2)) The angle i found allowed me construct a right angle triangle with which I used 1.2m or half the length of the tank as a side to calculate the opposide side or height. The answer i got was 120cm. (After subtracting 1.2m of water originally.) If anyone could help me with this question or verify the answer I would appreciate it.
