Suppose the coefficient of static friction between a penny and the back wall of a rocket car is 0.261. At what minimum rate (in m/s2) would the car have to accelerate so that a penny placed on the back wall would remain in place? Draw the coin's free-body diagram, find an expression for the normal force using the x-component of Newton's second law, and solve for the required acceleration using the y-component of Newton's second law after substituting fs, max = μsn. ___m/s^2
