Suppose that the metal cylinder were placed into a graduated cylinder filled with water, with markings of 1 ml, in order to find its volume by the amount of water it displaced, read to the nearest ±1 ml (note that i ml-1 cm) would this be less precise, more precise, or have approximately the same precision as calculating the volume from the given diameter and height measurements? 1 explain your reasoning.

The ballistic pendulum was invented in 1742 by english mathematician benjamin robins. it consists of an initially stationary pendulum that moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. the known variables are the bullet's mass m, the pendulum's mass m, and the height to which the block and bullet swing, determined by the length of the pendulum l and final angle θ. two principles of physics are necessary to solve for the bullet's original velocity. what are these principles? conservation of momentum and newton's third law conservation of energy and conservation of angular momentum grade summary deductions 0% potential 100% conservation of momentum and newton's second law. newton's second law and conservation of angular momentum. conservation of energy and newton's third law conservation of momentum and conservation of angular momentum. conservation of momentum and conservation of energy conservation of energy and newton's second law.

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.
