You have a quarter, mass m = 5.670 g, sliding across a table top at subway in the student union. your roommate's radar gun clocks its initial speed at vi = 4.7 m/s. the friction force on the quarter that slows it down has size 0.01 n. calculate the stopping distance to the nearest 0.01 m. e. g., if your answer is 8.837 m, then type 8.84 in the answer box.
