Title: Nautical Deceleration: Determining Initial Speed of a Boat; A boat of mass 3000 kg, travelling at a speed of um s”, is brought to rest in 20s by water resistance of 370 N. Find the value of u
In the realm of aquatic dynamics, our numerical exploration takes us aboard a boat with a mass of 3000 kg3000kg. This vessel, cruising with an initial speed denoted by � m/sum/s, encounters the resistance of water forces that halt its motion. The deceleration process unfolds over a span of 20 s20s, and the resisting force is quantified at 370 N370N. The crux of this exploration lies in uncovering the value of the boat’s initial speed (�u)—a parameter crucial for understanding the boat’s dynamic response to water resistance. Through the lens of Newtonian mechanics and fluid dynamics, this numerical quest promises insights into the aquatic journey of the boat and the impact of resisting forces on its deceleration.
