A sailboat is traveling east at 5m/s . A sudden gust of wind gives the boat an acceleration=.80 m/s^2, (40 degrees north of east).

A. What is the boat's speed 6 seconds later when the gust subsides?

________m/s

B. What is the boat's direction 6 seconds later when the gust subsides?

________degrees north of east.

My attempts:

v = v0 + at

v = (0) + (0.80m/s^2)* (6sec)

v = 4.8m/s

A^2+ B^2 = C^2

(4.8)^2 + (5.0)^2 = 48.04

C= 6.9 m/s

_____________________

tan-1 (4.8/5.0) = 44°

Please tell me what I did wrong? I am so stuck :(
