Homework Help: physics

Posted by Liz on Monday, September 24, 2012 at 4:10pm.

A model sailboat is slowly sailing west across a pond at 0.342 m/s. A gust of wind blowing at 28.7 south of west gives the sailboat a constant acceleration of magnitude 0.305 m/s2 during a time interval of 1.87 s. If the net force on the sailboat during the 1.87-s interval has magnitude 0.316 N, what is the sailboat's mass?
What is the new velocity of the boat after the 1.87 s gust of wind?
And what is the new direction of the boat after the 1.87 s gust of wind?
