 Question 2 Dimensional Motion ( Physics Forums Introductory Physics )Updated: 2010-08-02 17:00:56 (1)
 2 Dimensional Motion 1. The problem statement, all variables and given/known data A sailboat is traveling east at 5.0m/s. A sudden gust of wind gives the boat an acceleration a =(0.80m/s^2) (40 north of east). 2. Relevant equations What is the boat's speed 6\;s later when the gust subsides? I know the answer is 9.21m/s, but I am having difficulty breaking down the acceleration into its components. How would you start this problem and do I need to find Ax and Ay or am i going about this the wrong way. 3. The attempt at a solution So far I have Vx0= 5m/s Vy0= 0m/s t=6s Ax=? Ay=? and Think the equation I need to use is Vx= Vx0+Axt then do the same for Y and combine the two .

 2 Dimensional Motion Okay I figure it out i was doing it right but when it cam e to combining the two components i was just adding them instead of finding the magnitude for velocity. Which involve taking the sqaure root of the squares of the components. Squall
