g 1.90 kg textbook rests on a frictionless, horizontal surface. A cord attached to the book passes over a pulley whose diameter is 0.150 m, to a hanging book with mass 3.10 kg. The system is released from rest, and the books are observed to move 1.20 m in 0.900 s . Part A What is the tension in the part of the cord attached to the textbook? Express your answer with the appropriate units. T1 = nothing nothing Request Answer Part B What is the tension in the part of the cord attached to the hanging book? Express your answer with the appropriate units. T2 = nothing nothing Request Answer Part C What is the moment of inertia of the pulley about its rotation axis? Express your answer with the appropriate units. I = nothing nothing Request Answer Provide Feedback

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.
