A 100 kg cart with an initial velocity of +3 m/s has a force applied to it as it moves along a smooth horizontal floor. A graph of the horizontal force on the cart as a function of time is shown below. F(N) A B C 10 0+ 50+ O 3 t (s ) N 5 - 5+- - - It- - 50 - 100 - a. Rank the impulse applied to the cart by this force during the intervals A through C indicated on the graph, from greatest to least. Remember that + > 0> -. b. Find the velocity of the cart at time t = 6 seconds
