1. A golf ball is hit at an angle of 40 degrees to the horizontal at a velocity of 24 m/s. Calculate the Viy. 2. A golf ball is hit at an angle of 40 degrees to the horizontal at a velocity of 24 m/s. Calculate the Vix.

3. A firefighter, standing 45 m from a burning building, directs a stream of water from a ground level fire hose at an angle of 25 degrees above the horizontal. The Vi of the stream as it leaves the hose is 55 m/s. What is the water’s Vix?

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.

An observer that stands still as the electron moves by him, will observe
