A package rests on the back seat of your car.The coefficient of friction between the seat and the package is 0.24.Assuming you drive on a level road,what is the maximum acceleration your car can have if the package is to remain in place relative to your back seat? A)1.0 m/s² B)2.4 m/s² C)3.0 m/s² D)3.5 m/s²

The maximum acceleration without the package sliding is equal to the coefficient of static friction times the acceleration due to gravity (g = 9.8 m/s^2). Thus, maximum acceleration = 0.24 * 9.8 m/s^2 = 2.352 m/s^2, which is closest to 2.4 m/s^2.
