Homework Statement
A model sailboat is slowly sailing west across a pond at .33 m/s a gust of wind blowing at 28 degrees south of west gives the sailboat a constant acceleration of magnitude .30 m/s^2 during a time interval of 2.0 s (a) if the net force on the sailboat during the 2.0 s interval has magnitude .375 N, what is the sailboat's mass? (b) what is the new velocity of the boat after the 2.0-s gust of wind? (c) what is the new direction of the boat after the 2s gust of wind... ___ south of west.
Homework Equations
f=ma
vf=vo+at
tan^-1=vy/vx
The Attempt at a Solution
i have already determined a using f=ma .375 / .3 which is 1.25 kg
i have part b... by using vf= vo + at which is .930 m/s
but I am very confused with c! i think that i should be using tan^-1 (Vy/Vx) but i have no idea what to plug in. help please :(
