In Example 13.2 (p. 345), if instead the rocket launched from the Earth at 12,000 m/s, what would happen once it reached a distance infinitely far away from Earth. Group of answer choicesWhen this rocket is an infinite distance away from Earth, the rocket would have no kinetic energy and no gravitational potential energyThe rocket would not be able to reach deep space at this launch speedWhen this rocket is an infinite distance away from Earth, the rocket would have some kinetic energy and some gravitational potential energyWhen this rocket is an infinite distance away from Earth,, the rocket would have some kinetic energy and no gravitational potential energy

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 measurement of how fast an object moves relative to a reference point?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
