$5.$ A BC Ferry $($m $=13000\mathrm{.}0$ tonnes$)$ is traveling at $11$ m$/$s when the engines are put in reverse. The engines produce a force of $1\mathrm{.}0$ x $10^6$ N for a period of $20\mathrm{.}0$ seconds. a$.$ What is the magnitude of the impulse from the engine? What will be it's direction $($positive or negative?$)$ b$.$ What is the new momentum of the ferry? c$.$ What is the new velocity of the ferry? $($please clarify the difference between kg and tonnes when answering$)$
