You’re windsurfing at 6.28 m/s when a gust hits, accelerating your sailboard at 0.714 m/s2 at 48.8◦ to your original direction. If the gust lasts 5.42 s, what’s the magnitude of the board’s displacement during this time?

Which of the following is a true statement about the acceleration ~a of the pendulum bob ~a is equal to the acceleration due to gravity. ~a is perpendicular to the bob’s trajectory. ~a is equal to the instantaneous rate of change in velocity. ~a is tangent to the bob’s trajectory.
