A truck is carrying a 120-kg refrigerator, which is 2.20 m tall and 85.0 cm wide has its center of mass at its geometrical center. The refrigerator is facing sideways and a short strip on the bed of the truck keeps the refrigerator from sliding. What is the maximum acceleration that the truck can have before the refrigerator begins to tip over? A) 1.90 m/s² B) 4.17 m/s² C) 3.79 m/s² D) 7.58 m/s² E) 8.34 m/s²

Question

Quizplus · Accepted Answer

The refrigerator will begin to tip over when the torque due to the truck's acceleration about the edge of the base equals the torque due to gravity. Using the formula for torque and setting them equal gives the maximum acceleration as (g * width) / (2 * height), which calculates to approximately 3.79 m/s².
