1. The problem statement, all variables and given/known data 7. A 130-kg refrigerator that is 2.30 m tall and 90.0 cm wide is being delivered by a truck. The center of gravity of the refrigerator is located at its geometrical center and the refrigerator is facing sideways in the truck and is prevented from sliding. What is the maximum acceleration that the truck can have before the refrigerator begins to tip over? a. 4.17 m/s2 *b. 3.84 m/s2 c. 7.68 m/s2 d. 8.34 m/s2 2. Relevant equations a=v2/r 3. The attempt at a solution I have no idea what to do. I thought that the radius should be the distance between the center of mass and the center of the fridge when it starts moving, but in this case the radius will change (but it doesnt matter cause we want the start of the motion). I also think that it has to do with force and torque and breaking the equilibrium, but I dont know.
