A woman drives a car from one city to another with different constant speeds along the trip. She drives at a speed of 95.0 km/h for 15.0 min, 60.0 km/h for 20.0 min, makes a stop for 50.0 min, then continues at 40.0 km/h for 30.0 min, at which point she reaches her destination. (a) What is the total distance between her starting point and destination (in km)

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.
