A book sits on a horizontal top of a car which accelerates horizontally from rest. If the static coefficient of friction between car top and book is `0.45`, what is the maximum acceleration the car can have if the book does not slip ? `(g = 10 ms^(-2))`A. `50 ms^(-2)`B. `0.50 ms^(-2)`C. `44.1 m//sec^(2)`D. `4.5 ms^(-2)` |
