My 5 kg cat wants to push his box of kitty chow off the table so it will spill a snack for his afternoon "tea". The box has a mass of 1 kg (that's 2.2 lb or 9.8 N of gravitational downward force) and the coefficient of friction with the tabletop is 0.25.  About how much force does he have to push with to get the box to begin to slide? Pick the closest answer to what you calculate using your understanding of static frictional forces. A. 9.8 N B. 25 N C. 2.2 lb D. 2.5 N
