Question

You’re windsurfing at 7.3 m/s when a gust hits, accelerating your
sailboard at 0.82 m/s2 at 60° to your original direction. If the gust
lasts 8.7 s, what’s the board’s displacement during this time?

Answer 1

Change in momentum = Impulse = Force x time

So use this relationship to find the change in momentum of the sailboard.
