Arace car completes the final lap of a race on a 2-kilometer circular track. at the start of the lap, it crosses the line at 60 meters/second. it completes the lap 28.57 seconds later, crossing the line at 85 meters/second. calculate the displacement and average acceleration of the car along the track over the course of the final lap. a. displacement is 0 meters, and acceleration is 0.88 meters/second2. b. displacement is 2,000 meters, and acceleration is 1.14 meters/second2. c. displacement is 0 meters, and acceleration is 70.0 meters/second2. d. displacement is 2,000 meters, and acceleration is 80.0 meters/second2. e. displacement is 0 meters, and acceleration is 0.70 meters/second2.

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.
