Find the magnitude even though direction is correct?
1. The problem statement, all variables and given/known data
The force exerted by the wind on the sails of a sailboat is 490 N north. The water exerts a force of 250 N east. If the boat (including its crew) has a mass of 250 kg, what are the magnitude and direction of its acceleration?
2. Relevant equations
3. The attempt at a solution
Drew it out on a piece of paper:
So: (250, 490)
Direction = tan-1(490/250) = 62.96
Magnitude = V = SQRT(490^2+250^2) = 550 = Wrong?
Why would the magnitude be incorrect? Or can anyone point out where I may be wrong?
Edit - The answers are supposed to be in acceleration (m/s^2) and my magnitude came out to be:
550 Kg m/s^2 so I just divided by the kg and got my answer!
Silly mistake ;)
