Homework Statement
A sailboard is sailing at 6.5 when a gust of wind hits, causing it to accelerate at 0.48 at a 35 angle to its original direction of motion.
If the acceleration lasts 6.3 , what is the board's net displacement during the wind gust?
Homework Equations
Ok so far, I have drawn all of the motion graphs.
So I got
X Y
X_0= 0m Y_0= 0m
X_F=? Y_F=?
V_0x= 6.5m/s v_oy=0m/s
V_fy= 6.5m/s v_fy=?
a= 0 m/s^2 a= .48m/s^2
t= 6.3secs t=6.3secs
The Attempt at a Solution
And assuming those are correct. I got v_fy= 4.55 m/s by using 6.5tan35 = v_fy
then I used this equation: x=x_0+v_ot+(1/2)at^2 and got
X_f= 40.95m
Y_f= 9.5m
And then I added them together and then its 50.45m? Is this correct, because online it said it was wrong?
Thanks for helping!
