(Note that this acceleration is independent of mass.)Check Your Understanding At the time of its launch, the HMS Titanic was the most massive mobile object ever built, with a mass of 6.0107kg . If a force of 6 MN (6106N) was applied to the ship, what acceleration would it experience?A sailboat has a mass of 1.50103kg and is acted on by a force of 2.00103N toward the east, while the wind acts behind the sails with a force of 3.00103N in a direction 45 north of east. Find the magnitude and direction of the resulting acceleration.
