O řr and Fa and Ě, Submit Request Answer Usually the best advice is to choose a coordinate system so that the acceleration of the system is directly along one of the coordinate axes. If the system isn't accelerating, then you are better off choosing the coordinate system with the most vectors along the coordinate axes. But now you are gaing to ignore that advice.…
A 30 kg cannonball is shot at a sailing ship. When it hits the wooden sides of the ship, it just barely punches through the wooden hull, applying a 200 000 N force to the ship the whole time it was stopping. → If the cannonball was originally travelling at 300m/s, how long would it take to completely stop in the hull of the ship assuming constant acceleration.

Newton's first law states that: Group of answer choices Ia. n the absence of any net force acting on it, a mechanical system is necessarily at rest. b. In the absence of a non-zero net force acting on it, a mechanical system keeps moving in the same direction at the same speed (including the case v=0). c. For any pair A/B of objects interacting with one another, the force of A acting on B is the equal-opposite of the force of B acting on A. d. The rate of change of the velocity of a system is proportional to the net force acting on it.
